multiparty computation, depending on whether or not a
majority of the parties are assumed to be honest.
Protocols designed under this assumption provide `full
security' (and, in particular, guarantee output
delivery and fairness) when this assumption is correct;
however, if half or more of the parties are dishonest
then security is completely compromised. On the other
hand, protocols tolerating arbitrarily-many faults do
not provide fairness or guaranteed output delivery even
if only a single party is dishonest. It is natural to
wonder whether it is possible to achieve the `best of
both worlds': namely, a single protocol that
simultaneously achieves the best possible security in
both the above settings. Ishai, et al. (Crypto 2006)
recently addressed this question, and ruled out
constant-round protocols of this type.\par
As our main result, we completely settle the question
by ruling out protocols using any (expected) polynomial
number of rounds. Given this stark negative result, we
then ask what can be achieved if we are willing to
assume simultaneous message transmission (or,
equivalently, a non-rushing adversary). In this
setting, we show that impossibility still holds for
logarithmic-round protocols. We also show, for any
polynomial $p$, a protocol (whose round complexity
depends on $p$ ) that can be simulated to within

Specifically, we show the following bounds, which were

improvements in the more general models:* In the group

{$ n \lg^{O(1)} n $} requires {$ \Omega (\lg n \lg \lg

improvement over previous bounds, and matches known
upper bounds.* In the group model, a dynamic data
structure takes time {$ \Omega ((\lg n \lg \lg n)^2) $}
per operation. This is close to the {$ O(\lg^2 n) $}
upper bound, where as the previous lower bound was {$
\Omega (\lg n) $}.\par

abstract = "We introduce a new, generic framework for private data
analysis. The goal of private data analysis is to
release aggregate information about a data set while
protecting the privacy of the individuals whose
information the data set contains. Our framework allows
one to release functions $f$ of the data with
instance-based additive noise. That is, the noise
magnitude is determined not only by the function we
want to release, but also by the database itself. One
of the challenges is to ensure that the noise magnitude
does not leak information about the database. To
address that, we calibrate the noise magnitude to the
smooth sensitivity of $f$ on the database $x$ --- a
measure of variability of $f$ in the neighborhood of
the instance $x$. The new framework greatly expands the
applicability of output perturbation, a technique for
protecting individuals' privacy by adding a small
amount of random noise to the released statistics. To
our knowledge, this is the first formal analysis of the
effect of instance-based noise in the context of data
privacy.\par
Our framework raises many interesting algorithmic
questions. Namely,to apply the framework one must
compute or approximate the smooth sensitivity of $f$ on
$x$. We show how to do this efficiently for several
different functions, including the median and the cost
of the minimum spanning tree. We also give a generic
procedure based on sampling that allows one to release
$ f(x) $ accurately on many databases $x$. This
procedure is applicable even when no efficient
algorithm for approximating smooth sensitivity of $f$
is known or when $f$ is given as a black box. We
illustrate the procedure by applying it to $k$-SED
($k$-means) clustering and learning mixtures of
Gaussians.",

privacy in a statistical database. The second, growing
from an extensive literature on compressed sensing (see
in particular the work of Donoho and collaborators
[4,7,13,11])and explicitly connected to
error-correcting codes by Cand{\`e}s and Tao ([4]; see
also [5,3]), is in the use of linear programming for
error correction.\par
Our principal result is the discovery of a sharp
threshold $ \rho $ *$ \angle $ 0.239, so that if $ \rho
$ A is a random $ m \times n $ encoding matrix of
independently chosen standard Gaussians, where {$ m =
O(n) $}, then with overwhelming probability over choice
of {$A$}, for all {$ x \in R^n $}, LP decoding corrects
$ \lfloor \rho m \rfloor $ arbitrary errors in the
encoding {$ A x $}, while decoding can be made to fail
if the error rate exceeds $ \rho * $. Our bound
resolves an open question of Cand{\`e}s, Rudelson, Tao,
and Vershynin [3] and (oddly, but explicably) refutes
empirical conclusions of Donoho [11] and Cand{\`e}s et
al [3]. By scaling and rounding we can easily transform
these results to obtain polynomial-time decodable
random linear codes with polynomial-sized alphabets
tolerating any $ \rho $. \par
In the context of privacy-preserving datamining our
results say that any privacy mechanism, interactive or
non-interactive, providing reasonably accurate answers
to a 0.761 fraction of randomly generated weighted
subset sum queries, and arbitrary answers on the
remaining 0.239 fraction, is blatantly non-private.",

and Tardos (KKT) on the spread of influence in social
networks.\par
A social network can be represented by a directed graph
where the nodes are individuals and the edges indicate
a form of social relationship. A simple way to model
the diffusion of ideas, innovative behavior, or
`word-of-mouth' effects on such a graph is to consider
an increasing process of `infected' (or active) nodes:
each node becomes infected once an activation function
of the set of its infected neighbors crosses a certain
threshold value. Such a model was introduced by KKT in
[7,8] where the authors also impose several natural
assumptions: the threshold values are (uniformly)
random to account for our lack of knowledge of the true
values; and the activation functions are monotone and
submodular, i.e. have `diminishing returns.' The
monotonicity condition indicates that a node is more
likely to become active if more of its neighbors are
active, while the submodularity condition, indicates
that the marginal effect of each neighbor is decreasing
when the set of active neighbors increases.\par
For an initial set of active nodes $s$, let $ \sigma $
(S) denote the expected number of active nodes at
termination. Here we prove a conjecture of KKT: we show
that the function $ \sigma $ (S) is submodular under
the assumptions above. We prove the same result for the
expected value of any monotone, submodular function of
the set of active nodes at termination.\par
In other words, our results demonstrate that `local'
submodularity is preserved `globally' under diffusion
processes. This is of natural computational interest,
as many optimization problems have good approximation
algorithms for submodular functions. In particular, our
results coupled with an argument in [7] imply that a
greedy algorithm gives an $ (1 - 1 / e - \epsilon)
$-approximation algorithm for maximizing $ \sigma $ (S)
among all sets $s$ of a given size. This result has
important practical implications for many social
network analysis problems, notably viral marketing.",

a detailed understanding of the growth characteristics

this end, preferential attachment, in which the
popularity (or relevance) of a node is determined by
its degree, is a well-known and appealing random graph
model, whose predictions are in accordance with
experiments on the web graph and several social
networks. However, its central assumption, that the
popularity of the nodes depends only on their degree,
is not a realistic one, since every node has
potentially some intrinsic quality which can
differentiate its attractiveness from other nodes with
similar degrees.\par
In this paper, we provide a rigorous analysis of
preferential attachment with fitness, suggested by
Bianconi and Barab{\'a}si and studied by Motwani and
Xu, in which the degree of a vertex is scaled by its
quality to determine its attractiveness. Including
quality considerations in the classical preferential
attachment model provides a much more realistic
description of many complex networks, such as the web
graph, and allows to observe a much richer behavior in
the growth dynamics of these networks. Specifically,
depending on the shape of the distribution from which
the qualities of the vertices are drawn, we observe
three distinct phases, namely a first-mover-advantage
phase, a fit-get-richer phase and an
innovation-pays-off phase. We precisely characterize
the properties of the quality distribution that result
in each of these phases and we compute the exact growth
dynamics for each phase. The dynamics provide rich
information about the quality of the vertices, which
can be very useful in many practical contexts,

solvable using randomization when a process only has to

of routing the maximum possible number of
source-destination pairs on paths, such that at most {$
c(N) $} paths go through any edge. We show that the
problem is hard to approximate within an {$ N^\Omega (1
/ c(N)) $} factor even when we compare to the optimal
solution that routes pairs on edge-disjoint paths,
assuming NP doesn't have {$ N^{O(\log logN)} $}-time
randomized algorithms. Here the congestion {$ c(N) $}
can be any function in the range {$ 1 \leq c(N) \leq
\alpha \log N / \log \log N $} for some absolute
constant $ \alpha > 0 $. The hardness result is in the
right ballpark since a factor {$ N^{O(1 / c(N))} $}
approximation algorithm is known for this problem, via
rounding a natural multicommodity-flow relaxation. We
also give a simple integrality gap construction that
shows that the multicommodity-flow relaxation has an
integrality gap of {$ N^{\Omega (1 / c)} $} for $c$
ranging from $1$ to {$ \Theta ((\log n) / (\log \log

A solution to the routing problem involves selecting
which pairs to be routed and what paths to assign to
each routed pair. Two natural restrictions can be
placed on input instances to eliminate one of these
aspects of the problem complexity. The first
restriction is to consider instances with perfect
completeness; an optimal solution is able to route all
pairs with congestion 1 in such instances. The second
restriction to consider is the unique paths property
where each source-destination pair has a unique path
connecting it in the instance. An important aspect of
our result is that it holds on instances with any one
of these two restrictions. Our hardness construction
with the perfect completeness restriction allows us to
conclude that the directed congestion minimization
problem, where the goal is to route all pairs with
minimum congestion, is hard to approximate to within a
factor of {$ \Omega (\log N / \log \log N) $}. On the
other hand, the hardness construction with unique paths
property allows us to conclude an {$ N^{\Omega (1 / c)}

cardinality subset of edges whose removal separates all
source-sink pairs. The sparsest cut problem has the
same input, but the goal is to find a subset of edges
to delete so as to minimize the ratio of deleted edges
to the number of source-sink pairs that are separated
by this deletion. The natural linear programming
relaxation for multicut corresponds, by LP-duality, to
the well-studied maximum (fractional) multicommodity
flow problem, while the natural LP-relaxation for
sparsest cut corresponds to maximum concurrent flow.
Therefore, the integrality gap of the linear
programming relaxation for multicut/sparsest cut is
also the flow-cut gap: the maximum ratio, achievable
for any graph,between the maximum flow value and the
minimum cost solution for the corresponding cut
problem. Starting with the celebrated max flow-mincut
theorem of Ford and Fulkerson, flow-cut gaps have
played a central role in combinatorial optimization.
For many NP-hard network optimization problems, the
best known approximation guarantee corresponds to our
understanding of the appropriate flow-cut gap.\par
Our first result is that the flow-cut gap between
maximum multicommodity flow and minimum multicut is ~{$
\Omega $} (n$^{1 / 7}$ ) in directed graphs. We show a
similar result for the gap between maximum concurrent
flow and sparsest cut in directed graphs. These results
improve upon a long-standing lower bound of {$ \Omega

that these polynomially large flow-cut gaps are in a
sharp contrast to the undirected setting where both
these flow-cut gaps are known to be {$ \Theta (\log n)

and sparsest cut are hard to approximate to within a

any constant $ \epsilon > 0 $, unless NP $ \subseteq $

also show that existence of PCP's for NP with perfect

constant number of queries would imply a polynomial

abstract = "Compressed Sensing is a new paradigm for acquiring the
compressible signals that arise in many applications.
These signals can be approximated using an amount of
information much smaller than the nominal dimension of
the signal. Traditional approaches acquire the entire
signal and process it to extract the information. The
new approach acquires a small number of nonadaptive
linear measurements of the signal and uses
sophisticated algorithms to determine its information
content. Emerging technologies can compute these
general linear measurements of a signal at unit cost
per measurement.\par
This paper exhibits a randomized measurement ensemble
and a signal reconstruction algorithm that satisfy four
requirements: 1. The measurement ensemble succeeds for
all signals, with high probability over the random
choices in its construction. 2. The number of
measurements of the signal is optimal, except for a
factor polylogarithmic in the signal length. 3. The
running time of the algorithm is polynomial in the
amount of information in the signal and polylogarithmic
in the signal length. 4. The recovery algorithm offers
the strongest possible type of error guarantee.
Moreover, it is a fully polynomial approximation scheme
with respect to this type of error bound.\par
Emerging applications demand this level of performance.
Yet no other algorithm in the literature simultaneously
achieves all four of these desiderata.",

weight had been studied extensively. In a seminal paper
Azar et.al. showed that when $ m = n $ the most loaded
bin has {$ \Theta (\log \log n) $} balls with high
probability. Surprisingly, the gap in load between the
heaviest bin and the average bin does not increase with
$m$ and was shown by Berenbrink et al to be {$ \Theta
(\log \log n) $} with high probability for arbitrarily
large $m$. We generalize this result to the weighted
case where balls have weights drawn from an arbitrary
weight distribution. We show that as long as the weight
distribution has finite second moment and satisfies a
mild technical condition, the gap between the weight of
the heaviest bin and the weight of the average bin is
independent of the number balls thrown. This is
especially striking when considering heavy tailed
distributions such as Power-Law and Log-Normal
distributions. In these cases, as more balls are
thrown,heavier and heavier weights are encountered.
Nevertheless with high probability, the imbalance in
the load distribution does not increase. Furthermore,
if the fourth moment of the weight distribution is
finite, the expected value of the gap is shown to be
independent of the number of balls.",

such that one can probabilistically recover any bit $

codeword {$ C(x) $}, even after some constant fraction
of codeword bits has been corrupted. We give new
constructions of three query LDCs of vastly shorter
length than that of previous constructions.
Specifically, given any Mersenne prime $ p = 2^t - 1 $,
we design three query LDCs of length {$ N = (n^{1 / t})
$}, for every $n$. Based on the largest known Mersenne
prime, this translates to a length of less than $ \exp
(n^{10^{-7}}) $, compared to $ \exp (n^{1 / 2}) $ in
the previous constructions. It has often been
conjectured that there are infinitely many Mersenne
primes. Under this conjecture, our constructions yield
three query locally decodable codes of length {$ N =
\exp (n^{O(1 / (\log \log n))}) $} for infinitely many
$n$.\par
We also obtain analogous improvements for Private
Information Retrieval (PIR) schemes. We give 3-server
PIR schemes with communication complexity of {$
O(n^{10^{-7}}) $} to access an $n$-bit database,
compared to the previous best scheme with complexity {$
O(n^{1 / 5.25}) $}. Assuming again that there are
infinitely many Mersenne primes, we get 3-server PIR
schemes of communication complexity {$ n^{O(1 / (\log

Previous families of LDCs and PIR schemes were based on
the properties of low-degree multivariate polynomials

Theorem to obtain an explicit AC$^0$ circuit of depth 3

by Hopcroft and Tarjan lin1, which determines if a
given graph is planar in linear time.\par
Our algorithm can also be compared to the algorithms by
Mohar (STOC'96 and Siam J. Discrete Math 2001), for
testing the embeddability of an input graph in a fixed
surface. For each surface $s$, Mohar describes an
algorithm which yields either an embedding of {$G$} in
$s$ or a minor of {$G$} which is not embeddable in $s$
and is minimal with this property.\par
The same approach allows us to obtain linear time
algorithms for the same question for a variety of other
crossing numbers. We can also determine in linear time
if an input graph can be made planar by the deletion of
$k$ edges (for fixed $k$ ).",

Matching is interesting in its own right as a
nontrivial extension of non-bipartite min-cost
matching, its main value lies in many(seemingly very
different) problems that can be solved using our
algorithm. For example, suppose that we are given a
graph with terminal nodes, non-terminal nodes, and edge
costs. Then, the Terminal Backup problem, which
consists of finding the cheapest forest connecting
every terminal to at least one other terminal, is
reducible to Simplex Matching. Simplex Matching is also
useful for various tasks that involve forming groups of
at least two members, such as project assignment and
variants of facility location.\par
In an instance of Simplex Matching, we are given a
hypergraph {$H$} with edge costs, and edge size at most
3. We show how to find the min-cost perfect matching of
{$H$} efficiently, if the edge costs obey a simple and
realistic inequality that we call the SimplexCondition.

understand and implement, but difficult to prove

hardness vs. randomness tradeoff for BPP in the uniform
setting,which was subsequently extended to give optimal
tradeoffs for the full range of possible hardness
assumptions by Trevisan and Vadhan [29] (in a slightly
weaker setting). In 2003, Gutfreund,Shaltiel and
Ta-Shma [11] proved a uniform hardness vs. randomness
tradeoff for AM, but that result only worked on the
`high-end' of possible hardness assumptions.\par
In this work, we give uniform hardness vs. randomness
tradeoffs for AM that are near-optimal for the full
range of possible hardness assumptions. Following [11],
we do this by constructing a hitting-set-generator
(HSG) for AM with `resilient reconstruction.' Our
construction is a recursive variant of the
Miltersen-Vinodchandran HSG [24], the only known HSG
construction with this required property. The main new
idea is to have the reconstruction procedure operate
implicitly and locally on superpolynomially large
objects, using tools from PCPs(low-degree testing,
self-correction) together with a novel use of
extractors that are built from Reed--Muller codes [28,
26] for a sort of locally-computable error-reduction.
As a consequence we obtain gap theorems for AM (and AM
$ \cap $ coAM) that state, roughly, that either AM (or
AM $ \cap $ coAM)protocols running in time t(n) can
simulate all of EXP('Arthur--Merlin games are
powerful'), or else all of AM (or AM $ \cap $ coAM) can
be simulated in nondeterministic time s(n)

near-optimal relationship between t(n) and s(n). As in
GST, the case of AM $ \cap $ coAM yields a particularly

of the receiver's computation to the (potentially

Goldwasser et al. [14] in the area of program checking.
A classic example of such a sender-receiver setting is
interactive proof systems. By taking the sender to be a
(potentially malicious) prover and the receiver to be a
verifier, we show that ($p$-prover) interactive proofs
with $k$ rounds of interaction are equivalent to
($p$-prover) interactive proofs with k+O(1) rounds,
where the verifier is in NC$^0$. That is, each round of
the verifier's computation can be implemented in
constant parallel time. As a corollary, we obtain
interactive proof systems, with (optimally) constant
soundness, for languages in AM and NEXP, where the
verifier runs in constant parallel-time.\par
Another, less immediate sender-receiver setting arises
in considering error correcting codes. By taking the
sender to be a (potentially corrupted) codeword and the
receiver to be a decoder, we obtain explicit families
of codes that are locally (list-)decodable by
constant-depth circuits of size polylogarithmic in the
length of the codeword. Using the tight connection
between locally list-decodable codes and average-case

The previously best known factor for any non-trivial
class of lattices was {$ \gamma (n) = \tilde {O}(n)

Our results apply to families of lattices having
special algebraic structure. Specifically, we consider
lattices that correspond to ideals in the ring of
integers of an algebraic number field. The worst-case
problem we rely on is to find approximate shortest
vectors in these lattices, under an appropriate form of
preprocessing of the number field.\par
For the connection factors $ \gamma (n) $ we achieve,
the corresponding decision problems on ideal lattices
are not known to be NP-hard; in fact, they are in P.
However, the search approximation problems still appear
to be very hard. Indeed, ideal lattices are
well-studied objects in computational number theory,
and the best known algorithms for them seem to perform
no better than the best known algorithms for general
lattices.\par
To obtain the best possible connection factor, we
instantiate our constructions with infinite families of
number fields having constant root discriminant. Such
families are known to exist and are computable, though
no efficient construction is yet known. Our work
motivates the search for such constructions. Even
constructions of number fields having root discriminant
up to {$ O(n^{2 / 3 - \epsilon }) $} would yield
connection factors better than {$ \tilde {O}(n)

bound the number of required samples by {$ \tilde

constant $k$, and essentially the same bounds hold for
general $k$ ). To achieve these bounds, we use Fourier
analysis to relate a distribution's distance from
$k$-wise independence to its biases, a measure of the
parity imbalance it induces on a set of variables. The
relationships we derive are tighter than previously

abstract = "It is known that any quantum algorithm for Graph
Isomorphism that works within the framework of the
hidden subgroup problem (HSP) must perform highly
entangled measurements across {$ \Omega (n \log n) $}
coset states. One of the only known models for how such
a measurement could be carried out efficiently is
Kuperberg's algorithm for the HSP in the dihedral
group, in which quantum states are adaptively combined
and measured according to the decomposition of tensor
products into irreducible representations. This
`quantum sieve' starts with coset states, and works its
way down towards representations whose probabilities
differ depending on, for example, whether the hidden
subgroup is trivial or nontrivial.\par
In this paper we show that no such approach can produce
a polynomial-time quantum algorithm for Graph
Isomorphism. Specifically, we consider the natural
reduction of Graph Isomorphism to the HSP over the
wreath product {$ S_n \wreathproduct Z_2 $}. Using a
recently proved bound on the irreducible characters of
{$ S_n $}, we show that no algorithm in this family can
solve Graph Isomorphism in less than {$ e^{\Omega
(\sqrt {n})} $} time, no matter what adaptive rule it
uses to select and combine quantum states. In
particular, algorithms of this type can offer
essentially no improvement over the best known
classical algorithms, which run in time {$ e^{O(\sqrt
{n \log n})} $}.",

abstract = "In an online linear optimization problem, on each
period $t$, an online algorithm chooses {$ s_t \in S $}
from a fixed (possibly infinite) set {$S$} of feasible
decisions. Nature (who may be adversarial) chooses a
weight vector {$ w_t \in R $}, and the algorithm incurs
cost $ c(s_t, w_t) $, where $c$ is a fixed cost
function that is linear in the weight vector. In the
full-information setting, the vector $ w_t $ is then
revealed to the algorithm, and in the bandit setting,
only the cost experienced, $ c(s_t, w_t) $, is
revealed. The goal of the online algorithm is to
perform nearly as well as the best fixed {$ s \in S $}
in hindsight. Many repeated decision-making problems
with weights fit naturally into this framework, such as
online shortest-path, online TSP, online clustering,
and online weighted set cover.\par
Previously, it was shown how to convert any efficient
exact offline optimization algorithm for such a problem
into an efficient online bandit algorithm in both the
full-information and the bandit settings, with average
cost nearly as good as that of the best fixed {$ s \in
S $} in hindsight. However, in the case where the
offline algorithm is an approximation algorithm with
ratio $ \alpha > 1 $, the previous approach only worked
for special types of approximation algorithms. We show
how to convert any offline approximation algorithm for
a linear optimization problem into a corresponding
online approximation algorithm, with a polynomial
blowup in runtime. If the offline algorithm has an $
\alpha $-approximation guarantee, then the expected
cost of the online algorithm on any sequence is not
much larger than $ \alpha $ times that of the best {$ s
\in S $}, where the best is chosen with the benefit of
hindsight. Our main innovation is combining Zinkevich's
algorithm for convex optimization with a geometric
transformation that can be applied to any approximation
algorithm. Standard techniques generalize the above
result to the bandit setting, except that a
`Barycentric Spanner' for the problem is also
(provably) necessary as input. Our algorithm can also
be viewed as a method for playing large repeated games,
where one can only compute approximate best-responses,
rather than best-responses.",

input sequence of requests for service each of which
corresponds to a point in a metric space. The cost of
serving the requests heavily depends on the processing
order. Serving a request induces cost corresponding to
the distance between itself and the previously served
request, measured in the underlying metric space. A
reordering buffer with storage capacity $k$ can be used
to reorder the input sequence in a restricted fashion
so as to construct an output sequence with lower
service cost. This simple and universal framework is
useful for many applications in computer science and
economics, e.g., disk scheduling, rendering in computer
graphics, or painting shops in car plants.\par
In this paper, we design online algorithms for the
reordering buffer problem. Our main result is a
strategy with a polylogarithmic competitive ratio for
general metric spaces. Previous work on the reordering
buffer problem only considered very restricted metric
spaces. We obtain our result by first developing a
deterministic algorithm for arbitrary weighted trees
with a competitive ratio of {$ O(D \cdot \log k) $},
where {$D$} denotes the unweighted diameter of the
tree, i.e., the maximum number of edges on a path
connecting two nodes. Then we show how to improve this
competitive ratio to {$ O(\log^2 k) $} for metric
spaces that are derived from HSTs. Combining this
result with the results on probabilistically
approximating arbitrary metrics by tree metrics, we
obtain a randomized strategy for general metric spaces
that achieves a competitive ratio of {$ O(\log^2 k
\cdot \log n) $} in expectation against an oblivious
adversary. Here $n$ denotes the number of distinct
points in the metric space. Note that the length of the
input sequence can be much larger than $n$.",

existence of feasible fractional flow with node
congestion one implies the existence of a $d$-furcated
flow with congestion at most $ 1 + 1 / (d - 1) $, for $

gap for $d$-furcated flows is bounded and exactly equal
to $ 1 + 1 / (d - 1) $. For the case $ d = 1 $

is unbounded, namely {$ \Theta (\log n) $}. Thus,
allowing single-sink multicommodity network flows to
increase their maximum out degree from one to two
virtually eliminates this previously observed
congestion gap.\par
As a corollary we obtain a factor $ 1 + 1 / (d - 1)

architectures, we consider the following generalization
of the data stream model where the algorithm has
sequential access to multiple streams. Unlike the data
stream model, where the stream is read only, in this
new model (introduced in [8,9]) the algorithms can also
write onto streams. There is no limit on the size of
the streams but the number of passes made on the
streams is restricted. On the other hand, the amount of
internal memory used by the algorithm is scarce,
similar to data stream model.\par
We resolve the main open problem in [7] of proving
lower bounds in this model for algorithms that are
allowed to have 2-sided error. Previously, such lower
bounds were shown only for deterministic and 1-sided
error randomized algorithms [9,7]. We consider the
classical set disjointness problem that has proved to
be invaluable for deriving lower bounds for many other
problems involving data streams and other randomized
models of computation. For this problem, we show a
near-linear lower bound on the size of the internal
memory used by a randomized algorithm with 2-sided
error that is allowed to have o(\log N/\log \log N)
passes over the streams. This bound is almost optimal
since there is a simple algorithm that can solve this
problem using logarithmic memory if the number of
passes over the streams.\par
Applications include near-linear lower bounds on the
internal memory for well-known problems in the
literature:(1) approximately counting the number of
distinct elements in the input ({$ F_0 $}); (2)
approximating the frequency of the mod of an input
sequence ({$ F*_{\infty } $}); (3) computing the join
of two relations; and (4) deciding if some node of an
XML document matches an XQuery (or XPath) query. Our
techniques involve a novel direct-sum type of argument

players (who are not allowed to communicate) questions
sampled from some distribution and decides whether they
win or not based on some predicate of the questions and
their answers. The parallel repetition of the game is
the game in which the referee samples $n$ independent
pairs of questions and sends corresponding questions to
the players simultaneously. The players may now answer
each question in a way that depends on the other
questions they are asked.\par
If the players cannot win the original game with
probability better than $ (1 - \epsilon) $, what's the
best they can do in the repeated game? We improve
earlier results of Raz and Holenstein, which showed
that the players cannot win all copies in the repeated
game with probability better than {$ (1 -
\epsilon^3)^{\Omega (n / c)} $} (here $c$ is the length
of the answers in the game), in the following ways: We
prove the bound {$ (1 - \epsilon^2)^{\Omega (n)} $} as
long as the game is a `projection game', the type of
game most commonly used in hardness of approximation
results. Our bound is independent of the answer length
and has a better dependence on $ \epsilon $. By the
recent work of Raz, this bound is essentially tight. A
consequence of this bound is to the Unique Games
Conjecture of Khot. Many tight or almost tight hardness
of approximation results have been proved using the
Unique Games Conjecture, so it would be very
interesting to prove this conjecture. We make progress
towards this goal by showing that it suffices to prove
the following easier statement: {Unique Games
Conjecture} For every $ \delta $, $ \epsilon > 0 $,
there exists an alphabet size {$ M(\epsilon) $} such
that it is NP-hard to distinguish a Unique Game with
alphabet size {$M$} for which a $ 1 - \epsilon^2 $
fraction of the constraints can be satisfied from one
in which a $ 1 - \epsilon^{1 - \delta } $ fraction of
the constraints can be satisfied. We also prove a
concentration bound for parallel repetition (of general
games) showing that for any constant $ 0 < \delta <
\epsilon $, the probability that the players win a $ (1
- \epsilon + \delta) $ fraction of the games in the
parallel repetition is at most {$ \exp ( - \Omega
(\delta^4 n / c)) $}. An application of this is in
testing Bell Inequalities. Our result implies that the
parallel repetition of the CHSH game can be used to get
an experiment that has a very large classical versus

equivalent to the `sparse approximation' problem of
approximating signals concisely. The subset selection
problem is NP-hard in general; in this paper, we
propose and analyze exact and approximation algorithms
for several special cases of practical interest.
Specifically, we give an FPTAS when the covariance
matrix has constant bandwidth, and exact algorithms
when the associated covariance graph, consisting of
edges for pairs of variables with non-zero correlation,
forms a tree or has a large (known) independent set.
Furthermore, we give an exact algorithm when the
variables can be embedded into a line such that the
covariance decreases exponentially in the distance, and
a constant-factor approximation when the variables have
no `conditional suppressor variables'. Much of our
reasoning is based on perturbation results for the R^2
multiple correlation measure, which is frequently used
as a natural measure for `goodness-of-fit statistics'.
It lies at the core of our FPTAS, and also allows us to
extend our exact algorithms to approximation algorithms
when the matrix `nearly' falls into one of the above

Assuming that player $i$ receives a set of items {$ S_i

oracle model where the only access to the utility

a special case of the more general problem of
submodular maximization subject to a matroid
constraint: {$ \max {f(S) : S \in I} $}, where $f$ is
monotone submodular and {$I$} is the collection of
independent sets in some matroid.\par
For both problems, a greedy algorithm is known to yield
a 1/2-approximation [21, 16]. In special cases where
the matroid is uniform ({$ I = S : |S| \leq k $}) [20]

a $ (1 - 1 / e) $-approximation has been achieved and
this is optimal for these problems in the value oracle

is, however, a fundamental disconnect between the
traditional application domains of mechanism design

science (such as networks): while monetary `transfers'
(i.e., payments) are essential for most of the known
positive results in mechanism design, they are
undesirable or even technologically infeasible in many
computer systems. Classical impossibility results imply
that the reach of mechanisms without transfers is
severely limited. Computer systems typically do have
the ability to reduce service quality--routing systems
can drop or delay traffic, scheduling protocols can
delay the release of jobs, and computational payment
schemes can require computational payments from users
(e.g., in spam-fighting systems). Service degradation
is tantamount to requiring that users `burn money', and
such `payments' can be used to influence the
preferences of the agents at a cost of degrading the
social surplus. We develop a framework for the design
and analysis of `money-burning mechanisms' to maximize
the residual surplus-the total value of the chosen
outcome minus the payments required. Our primary
contributions are the following. * We define a general
template for prior-free optimal mechanism design that
explicitly connects Bayesian optimal mechanism design,
the dominant paradigm in economics, with worst-case
analysis. In particular, we establish a general and
principled way to identify appropriate performance
benchmarks in prior-free mechanism design. * For
general single-parameter agent settings, we
characterize the Bayesian optimal money-burning
mechanism. * For multi-unit auctions, we design a
near-optimal prior-free money-burning mechanism: for
every valuation profile, its expected residual surplus
is within a constant factor of our benchmark, the
residual surplus of the best Bayesian optimal mechanism
for this profile. * For multi-unit auctions, we
quantify the benefit of general transfers over
money-burning: optimal money-burning mechanisms always
obtain a logarithmic fraction of the full social

model with and without prior entanglement. This was
proved by the multidimensional discrepancy method. We
give an entirely different proof of Razborov's result,
using the original, one-dimensional discrepancy method.
This refutes the commonly held intuition (Razborov
2003) that the original discrepancy method fails for
functions such as DISJOINTNESS. More importantly, our
communication lower bounds hold for a much broader
class of functions for which no methods were available.
Namely, fix an arbitrary function f:{0,1}$^{n / 4}$
->{0,1} and let A be the Boolean matrix whose columns
are each an application of $f$ to some subset of the

the communication complexity of A in the bounded-error
quantum model with and without prior entanglement is {$
\Omega (d) $}, where $d$ is the approximate degree of

easily. Our result also establishes a large new class

is a new construction of suitably structured matrices

languages. The (honest) prover should be efficient and
run in polynomial time, or in other words a `muggle'.
The verifier should be super-efficient and run in
nearly-linear time. These proof systems can be used for
delegating computation: a server can run a computation
for a client and interactively prove the correctness of
the result. The client can verify the result's
correctness in nearly-linear time (instead of running
the entire computation itself). Previously, related
questions were considered in the Holographic Proof
setting by Babai, Fortnow, Levin and Szegedy, in the
argument setting under computational assumptions by
Kilian, and in the random oracle model by Micali. Our
focus, however, is on the original interactive proof
model where no assumptions are made on the
computational power or adaptiveness of dishonest
provers. Our main technical theorem gives a public coin
interactive proof for any language computable by a
log-space uniform Boolean circuit with depth $d$ and
input length $n$. The verifier runs in time $ (n + d)
\times \polylog (n) $ and space {$ O(\log (n)) $}, the
communication complexity is $ d \times \polylog (n) $,
and the prover runs in time $ \poly (n) $. In
particular, for languages computable by log-space
uniform NC (circuits of $ \polylog (n) $ depth), the
prover is efficient, the verifier runs in time $ n
\times \polylog (n) $ and space {$ O(\log (n)) $}, and
the communication complexity is $ \polylog (n) $. Using
this theorem we make progress on several questions: We
show how to construct short (polylog size)
computationally sound non-interactive certificates of
correctness for any log-space uniform NC computation,
in the public-key model. The certificates can be
verified in quasi-linear time and are for a designated
verifier: each certificate is tailored to the
verifier's public key. This result uses a recent
transformation of Kalai and Raz from public-coin
interactive proofs to one-round arguments. The
soundness of the certificates is based on the existence
of a PIR scheme with polylog communication. Interactive
proofs with public-coin, log-space, poly-time verifiers
for all of P. This settles an open question regarding
the expressive power of proof systems with such
verifiers. Zero-knowledge interactive proofs with
communication complexity that is quasi-linear in the
witness, length for any NP language verifiable in NC,

communicate meaningfully, without any common language
or background? This question has interest on its own,
but is especially relevant in the context of modern
computational infrastructures where an increase in the
diversity of computers is making the task of
inter-computer interaction increasingly burdensome.
Computers spend a substantial amount of time updating
their software to increase their knowledge of other
computing devices. In turn, for any pair of
communicating devices, one has to design software that
enables the two to talk to each other. Is it possible
instead to let the two computing entities use their
intelligence (universality as computers) to learn each
others' behavior and attain a common understanding?
What is `common understanding?' We explore this
question in this paper.\par
To formalize this problem, we suggest that one should
study the `goal of communication:' why are the two
entities interacting with each other, and what do they
hope to gain by it? We propose that by considering this
question explicitly, one can make progress on the
question of universal communication.\par
We start by considering a computational setting for the
problem where the goal of one of the interacting
players is to gain some computational wisdom from the
other player. We show that if the second player is
`sufficiently' helpful and powerful, then the first
player can gain significant computational power
(deciding PSPACE complete languages).\par

underlying the task of formalizing universal
communication, but also suggests some interesting
phenomena and highlights potential tools that may be

self-testing were pioneered by [Blum and Kannan] and
[Blum, Luby and Rubinfeld] in the mid eighties as a new
way to gain confidence in software, by considering
program correctness on an input by input basis rather
than full program verification. Work in the field of
program checking focused on designing, for specific
functions, checkers, testers and correctors which are
more efficient than the best program known for the
function. These were designed utilizing specific
algebraic, combinatorial or completeness properties of
the function at hand. In this work we introduce a novel
composition methodology for improving the efficiency of
program checkers. We use this approach to design a
variety of program checkers that are provably more
efficient, in terms of circuit depth, than the optimal
program for computing the function being checked.
Extensions of this methodology for the cases of program
testers and correctors are also presented. In
particular, we show: For all $ i \geq 1 $, every
language in RNC$^i$ (that is NCO-hard under
NCZ-reductions) has a program checker in RNC$^{i - 1}$.
In addition, for all $ i \geq 1 $, every language in
RNC$^i$ (that is NCO-hard under ACZ-reductions) has a
program corrector, tester and checker in RAC$^{i - 1}$.
This is the first time checkers are designed for a wide
class of functions characterized only by its
complexity, rather than by algebraic or combinatorial
properties. This characterization immediately yields
new and efficient checkers for languages such as graph
connectivity, perfect matching and bounded-degree graph
isomorphism. Constant-depth checkers, testers and
correctors for matrix multiplication, inversion,
determinant and rank. All previous program checkers,
testers and correctors for these problems run in nearly
logarithmic depth. Moreover, except for matrix
multiplication, they all require the use of the library
notion of [Blum-Luby-Rubinfeld], in which checkers have
access to a library of programs for various matrix
functions, rather than only having access to a program
for the function being checked. Furthermore, we provide
conditions under which program libraries can be
eliminated. Important ingredients in these results are
new and very efficient checkers for complete languages
in low complexity classes (e.g. NCO). These
constructions are based on techniques that were
developed in the field of cryptography.",

role in the design of approximation and online
algorithms for graph problems. This is mainly due to
the fact that the results concerning the approximation
of metric spaces by tree metrics (e.g. [10,11,14,16])
depend on hierarchical graph decompositions. In this
line of work a probability distribution over tree
graphs is constructed from a given input graph, in such
a way that the tree distances closely resemble the
distances in the original graph. This allows it, to
solve many problems with a distance-based cost function
on trees, and then transfer the tree solution to
general undirected graphs with only a logarithmic loss
in the performance guarantee. The results about
oblivious routing [30,22] in general undirected graphs
are based on hierarchical decompositions of a different
type in the sense that they are aiming to approximate
the bottlenecks in the network (instead of the
point-to-point distances). We call such decompositions
cut-based decompositions. It has been shown that they
also can be used to design approximation and online
algorithms for a wide variety of different problems,
but at the current state of the art the performance
guarantee goes down by an {$ O(\log^2 n \log \log n)
$}-factor when making the transition from tree networks
to general graphs. In this paper we show how to
construct cut-based decompositions that only result in
a logarithmic loss in performance, which is
asymptotically optimal. Remarkably, one major
ingredient of our proof is a distance-based
decomposition scheme due to Fakcharoenphol, Rao and
Talwar [16]. This shows an interesting relationship
between these seemingly different decomposition
techniques. The main applications of the new
decomposition are an optimal {$ O(\log n)
$}-competitive algorithm for oblivious routing in
general undirected graphs, and an {$ O(\log n)

the {$ O(\log^{1.5} n) $} approximation by Feige and

local list-decoding algorithm produces a list
containing all degree $r$ polynomials within relative

The list size could be exponential in $m$ at radius $
2^{-r} $, so our bound is optimal in the local setting.
Since {$ {\rm RM}(2, m) $} has relative distance $
2^{-r} $, our algorithm beats the Johnson bound for $ r
\geq 2 $.\par
In the setting where we are allowed running-time
polynomial in the block-length, we show that
list-decoding is possible up to even larger radii,
beyond the minimum distance. We give a deterministic
list-decoder that works at error rate below {$ J(2^{1 -

basic settings are still rich with unresolved
questions. In particular, consider a set of agents who
engage in bargaining with one another,but instead of
pairs of agents interacting in isolation,agents have
the opportunity to choose whom they want to negotiate
with, along the edges of a graph representing
social-network relations. The area of network exchange
theory in sociology has developed a large body of
experimental evidence for the way in which people
behave in such network-constrained bargaining
situations, and it is a challenging problem to develop
models that are both mathematically tractable and in
general agreement with the results of these
experiments.\par
We analyze a natural theoretical model arising in
network exchange theory, which can be viewed as a
direct extension of the well-known Nash bargaining
solution to the case of multiple agents interacting on
a graph. While this generalized Nash bargaining
solution is surprisingly effective at picking up even
subtle differences in bargaining power that have been
observed experimentally on small examples, it has
remained an open question to characterize the values
taken by this solution on general graphs, or to find an
efficient means to compute it.\par
Here we resolve these questions, characterizing the
possible values of this bargaining solution, and giving
an efficient algorithm to compute the set of possible
values. Our result exploits connections to the

equilibrium prices? In an effort to shed light on this
question from an algorithmic perspective, this paper
formalizes the setting of Ongoing Markets, by contrast
with the classic market scenario, which we term
One-Time Markets. The Ongoing Market allows trade at
non-equilibrium prices, and, as its name suggests,
continues over time. As such, it appears to be a more
plausible model of actual markets.\par
For both market settings, this paper defines and
analyzes variants of a simple tatonnement algorithm
that differs from previous algorithms that have been
subject to asymptotic analysis in three significant
respects: the price update for a good depends only on
the price, demand, and supply for that good, and on no
other information; the price update for each good
occurs distributively and asynchronously; the
algorithms work (and the analyses hold) from an
arbitrary starting point.\par
Our algorithm introduces a new and natural update rule.
We show that this update rule leads to fast convergence
toward equilibrium prices in a broad class of markets
that satisfy the weak gross substitutes property. These
are the first analyses for computationally and
informationally distributed algorithms that demonstrate
polynomial convergence.\par
Our analysis identifies three parameters characterizing
the markets, which govern the rate of convergence of
our protocols. These parameters are, broadly speaking:
1. A bound on the fractional rate of change of demand
for each good with respect to fractional changes in its
price. 2. A bound on the fractional rate of change of
demand for each good with respect to fractional changes
in wealth. 3. The closeness of the market to a Fisher
market (a market with buyers starting with money
alone).\par
We give two types of protocols. The first type assumes
global knowledge of only (an upper bound on) the first
parameter. For this protocol, we also provide a
matching lower bound in terms of these parameters for
the One-Time Market. Our second protocol, which is
analyzed for the One-Time Market alone, assumes no
global knowledge whatsoever.",

In this paper, we therefore study the complexity of

An alpha-approximate equilibrium, for $ \alpha $ > 1,
is a state of the game in which none of the players can
make an $ \alpha $-greedy step, i.e., an unilateral
strategy change that decreases the player's cost by a
factor of at least $ \alpha $. Our main result shows
that finding an $ \alpha $-approximate equilibrium of a

polynomial-time computable $ \alpha $ > 1. Our analysis
is based on a gap introducing PLS-reduction from FLIP,
i.e., the problem of finding a local optimum of a
function encoded by an arbitrary circuit. As this
reduction is tight it additionally implies that
computing an $ \alpha $-approximate equilibrium
reachable from a given initial state by a sequence of $
\alpha $-greedy steps is PSPACE-complete. Our results
are in sharp contrast to a recent result showing that
every local search problem in PLS admits a fully

the price of anarchy: Rather than assume that
self-interested players will play according to a Nash
equilibrium (which may even be computationally hard to
find), we assume only that selfish players play so as
to minimize their own regret. Regret minimization can
be done via simple, efficient algorithms even in many
settings where the number of action choices for each
player is exponential in the natural parameters of the
problem. We prove that despite our weakened
assumptions, in several broad classes of games, this
`price of total anarchy' matches the Nash price of
anarchy, even though play may never converge to Nash
equilibrium. In contrast to the price of anarchy and
the recently introduced price of sinking, which require
all players to behave in a prescribed manner, we show
that the price of total anarchy is in many cases
resilient to the presence of Byzantine players, about
whom we make no assumptions. Finally, because the price
of total anarchy is an upper bound on the price of
anarchy even in mixed strategies, for some games our
results yield as corollaries previously unknown bounds
on the price of anarchy in mixed strategies.",

tested play a central role in property testing. We
support this assertion in the context of algebraic
functions, by examining properties of functions mapping
a vector space {$ K^n $} over a field {$K$} to a
subfield {$F$}. We consider ({$F$}-)linear properties
that are invariant under linear transformations of the
domain and prove that an {$ O(1) $}-local
`characterization' is a necessary and sufficient
condition for {$ O(1) $}-local testability. when {$ |K|
= O(1) $}. (A local characterization of a property is a
definition of a property in terms of local constraints
satisfied by functions exhibiting a property.) For the
subclass of properties that are invariant under {\em
affine\/} transformations of the domain, we prove that
the existence of a single {$ O(1) $}-local constraint
implies {$ O(1) $}-local testability. These results
generalize and extend the class of algebraic
properties, most notably linearity and low-degree-ness,
that were previously known to be testable. In
particular, the extensions include properties satisfied
by functions of degree linear in $n$ that turn out to
be {$ O(1) $}-locally testable. Our results are proved
by introducing a new notion that we term `formal
characterizations'. Roughly this corresponds to
characterizations that are given by a single local
constraint and its permutations under linear
transformations of the domain. Our main testing result
shows that local formal characterizations essentially
imply local testability. We then investigate properties
that are linear-invariant and attempt to understand
their local formal characterizability. Our results here
give coarse upper and lower bounds on the locality of
constraints and characterizations for linear-invariant
properties in terms of some structural parameters of
the property we introduce. The lower bounds rule out
any characterization, while the upper bounds give
formal characterizations. Combining the two gives a
test for all linear-invariant properties with local
characterizations. We believe that invariance of
properties is a very interesting notion to study in the
context of property testing in general and merits a
systematic study. In particular, the class of
linear-invariant and affine-invariant properties
exhibits a rich variety among algebraic properties and
offer better intuition about algebraic properties than
the more limited class of low-degree functions.",

Cleve (STOC 1986) showed that complete fairness cannot
be achieved in general in the two-party setting;
specifically, he showed (essentially) that it is
impossible to compute Boolean XOR with complete
fairness. Since his work, the accepted folklore has
been that nothing non-trivial can be computed with
complete fairness, and the question of complete
fairness in secure two-party computation has been
treated as closed since the late '80s.\par
In this paper, we demonstrate that this widely held
folklore belief is false by showing completely-fair
secure protocols for various non-trivial two-party
functions including Boolean AND/OR as well as Yao's
`millionaires' problem'. Surprisingly, we show that it
is even possible to construct completely-fair protocols

typically involve a large multiplicative computational
overhead that grows with the desired level of security.
We explore the possibility of implementing basic
cryptographic primitives, such as encryption,
authentication, signatures, and secure two-party
computation, while incurring only a constant
computational overhead compared to insecure
implementations of the same tasks. Here we make the
usual security requirement that the advantage of any
polynomial-time attacker must be negligible in the
input length.\par
We obtain affirmative answers to this question for most
central cryptographic primitives under plausible,
albeit sometimes nonstandard, intractability
assumptions. We start by showing that
pairwise-independent hash functions can be computed by
linear-size circuits, disproving a conjecture of
Mansour, Nisan, and Tiwari (STOC 1990). This
construction does not rely on any unproven assumptions
and is of independent interest. Our hash functions can
be used to construct message authentication schemes
with constant overhead from any one-way function. Under
an intractability assumption that generalizes a
previous assumption of Alekhnovich (FOCS 2003), we get
(public and private key) encryption schemes with
constant overhead. Using an exponentially strong
version of the previous assumption, we get signature
schemes of similar complexity. Assuming the existence
of pseudorandom generators in NC $z$ with polynomial
stretch together with the existence of an (arbitrary)
oblivious transfer protocol, we get similar results for
the seemingly very complex task of secure two-party
computation. More concretely, we get general protocols
for secure two-party computation in the semi-honest
model in which the two parties can be implemented by
circuits whose size is a constant multiple of the size
$s$ of the circuit to be evaluated. In the malicious
model, we get protocols whose communication complexity
is a constant multiple of $s$ and whose computational
complexity is slightly super-linear in $s$. For natural
relaxations of security in the malicious model that are
still meaningful in practice, we can also keep the
computational complexity linear in $s$. These results
extend to the case of a constant number of parties,
where an arbitrary subset of the parties can be
corrupted.\par

suggest the intriguing possibility that the ultimate
efficiency in this area of cryptography can be obtained

accelerating traditional interior point algorithms by
quickly solving the system of linear equations that

improvement of roughly {$ O(n / m^{1 / 2}) $} over

observe that these belong to the family of symmetric

solving a linear system in a symmetric {$M$}-matrix to
that of solving {$ O(\log n) $} linear systems in

identity testing (PIT) and reconstruction of read-once
formulas. The following are some deterministic
algorithms that we obtain. An {$ n^{O(k^2)} $}
algorithm for checking whether given $k$ ROFs sum to
zero or not. An {$ n^{O(d + k^2)} $} time algorithm for
checking whether a black box holding the sum of $k$
depth $d$ ROFs computes the zero polynomial. In other
words, we provide a hitting set of size {$ n^{O(d +
k^2)} $} for the sum of $k$ depth $d$ ROFs. This
implies an {$ n^{O(d)} $} deterministic algorithm for
the reconstruction of depth $d$ ROFs. A hitting set of
size {$ \exp (\tilde {O}(\sqrt {n} + k^2)) $} for the
sum of $k$ ROFs (without depth restrictions). This
implies a sub-exponential time deterministic algorithm
for black-box identity testing and reconstructing of
ROFs. To the best of our knowledge our results give the
first polynomial time (non black-box) and
sub-exponential time (black-box) identity testing
algorithms for the sum of (a constant number of) ROFs.
In addition, we introduce and study the read-once
testing problem (ROT for short): Given an arithmetic
circuit computing a polynomial P(x), decide whether
there is a ROF computing P(x). If there is such a
formula then output it. Otherwise output `No'. We show
that most previous algorithms for polynomial identity
testing can be strengthen to yield algorithms for the
ROT problem. In particular we give ROT algorithms for:
Depth-2 circuits (circuits computing sparse
polynomials), Depth-3 circuits with bounded top fan-in
(both in the black-box and non black-box settings,
where the running time depends on the model),
non-commutative formulas and sum of $k$ ROFs. The
running time of the ROT algorithm is essentially the
same running time as the corresponding PIT algorithm
for the class. The main tool in most of our results is
a new connection between polynomial identity testing
and reconstruction of read-once formulas. Namely, we
show that in any model that is closed under partial
derivatives (that is, a partial derivative of a
polynomial computed by a circuit in the model, can also
be computed by a circuit in the model) and that has an
efficient deterministic polynomial identity testing
algorithm, we can also answer the read-once testing
problem.",

abstract = "In the 2nd Annual FOCS (1961), C. K. Chow proved that
every Boolean threshold function is uniquely determined
by its degree-0 and degree-1 Fourier coefficients.
These numbers became known as the Chow Parameters.
Providing an algorithmic version of Chow's theorem ---
i.e., efficiently constructing a representation of a
threshold function given its Chow Parameters --- has
remained open ever since. This problem has received
significant study in the fields of circuit complexity,
game theory and the design of voting systems, and
learning theory. In this paper we effectively solve the
problem, giving a randomized PTAS with the following
behavior: Theorem: Given the Chow Parameters of a
Boolean threshold function $f$ over $n$ bits and any
constant $ \epsilon $ > 0, the algorithm runs in time
{$ O(n^2 \log^2 n) $} and with high probability outputs
a representation of a threshold function $ f' $ which
is $ \epsilon $-close to $f$. Along the way we prove
several new results of independent interest about
Boolean threshold functions. In addition to various
structural results, these include the following new
algorithmic results in learning theory (where threshold
functions are usually called `halfspaces'): An {$
\tilde {O}(n^2) $}-time uniform distribution algorithm
for learning halfspaces to constant accuracy in the
`Restricted Focus of Attention' (RFA) model of
Ben-David et al. [3]. This answers the main open
question of [6]. An {$ O(n^2) $}-time agnostic-type
learning algorithm for halfspaces under the uniform
distribution. This contrasts with recent results of
Guruswami and Raghavendra [21] who show that the
learning problem we solve is NP-hard under general
distributions. As a special case of the latter result
we obtain the fastest known algorithm for learning
halfspaces to constant accuracy in the uniform
distribution PAC learning model. For constant $
\epsilon $ our algorithm runs in time ~O(n^2), which
substantially improves on previous bounds and nearly
matches the {$ \Omega (n^2) $} bits of training data
that any successful learning algorithm must use.",

that if a Boolean function $ f : {0, 1}^n \rightarrow

small circuits, then the corresponding $k$-wise direct
product function $ f^k(x_1, \ldots {}, x_k) = (f(x_1),
\ldots {}, f(x_k)) $ (where each $ x_i \rightarrow {0,
1}^n $ ) is significantly harder to compute on average
by slightly smaller circuits. We prove a fully uniform
version of the Direct-Product Theorem with
information-theoretically optimal parameters, up to
constant factors. Namely, we show that for given $k$
and $ \epsilon $, there is an efficient randomized
algorithm {$A$} with the following property. Given a
circuit {$C$} that computes $ f^k $ on at least $
\epsilon $ fraction of inputs, the algorithm A outputs
with probability at least $ 3 / 4 $ a list of {$ O(1 /
\epsilon) $} circuits such that at least one of the
circuits on the list computes $f$ on more than $ 1 -
\delta $ fraction of inputs, for {$ \delta = O((\log 1
/ \epsilon) / k) $}. Moreover, each output circuit is
an AC$^0$ circuit (of size $ \poly (n, k, \log 1 /
\delta, 1 / \epsilon) $ ), with oracle access to the
circuit {$C$}. Using the Goldreich--Levin decoding
algorithm [5], we also get a fully uniform version of
Yao's XOR Lemma [18] with optimal parameters, up to
constant factors. Our results simplify and improve
those in [10]. Our main result may be viewed as an
efficient approximate, local, list-decoding algorithm
for direct-product codes (encoding a function by its
values on all $k$-tuples) with optimal parameters. We
generalize it to a family of `derandomized'
direct-product codes, which we call intersection codes,
where the encoding provides values of the function only
on a subfamily of $k$-tuples. The quality of the
decoding algorithm is then determined by sampling
properties of the sets in this family and their
intersections. As a direct consequence of this
generalization we obtain the first derandomized direct
product result in the uniform setting, allowing
hardness amplification with only constant (as opposed
to a factor of $k$ ) increase in the input length.
Finally, this general setting naturally allows the
decoding of concatenated codes, which further yields
nearly optimal derandomized amplification.",

converting a $ \delta $-hard function $ f : (0, 1)^n
\rightarrow (0, 1) $ into a ($ 1 / 2 - \epsilon $
)-hard function {$ \Amp (f) $}, where $f$ is $ \gamma
$-hard if small circuits fail to compute $f$ on at
least a $ \gamma $ fraction of the inputs. Typically, $
\epsilon $, $ \delta $ are small (and $ \delta = 2^{-k}
$ captures the case where $f$ is worst-case hard).
Achieving {$ \epsilon = 1 / n^{\Omega (1)} $} is a
prerequisite for cryptography and most
pseudorandom-generator constructions.\par
In this paper we study the complexity of black-box
proofs of hardness amplification. A class of circuits
cal {$D$} {\em proves\/} a hardness amplification
result if for any function $h$ that agrees with {$ \Amp
(f) $} on a $ 1 / 2 + e $ fraction of the inputs there
exists an oracle circuit {$ D \in D $} such that {$ D^h
$} agrees with $f$ on a $ 1 - \delta $ fraction of the
inputs. We focus on the case where every {$ D \in D $}
makes {\em non-adaptive\/} queries to $h$. This setting
captures most hardness amplification techniques. We
prove two main results:\par
(1) The circuits in {$D$} `can be used' to compute the
majority function on $ 1 / \epsilon $ bits. In
particular, these circuits have large depth when $
\epsilon \leq 1 / \poly \log n $. \par
(2) The circuits in {$D$} must make {$ \Omega \log (1 /
\delta) / e^2 $} oracle queries.\par
Both our bounds on the depth and on the number of
queries are tight up to constant factors.\par
Our results explain why hardness amplification
techniques have failed to transform known lower bounds
against constant-depth circuit classes into strong
average-case lower bounds. When coupled with the
celebrated `Natural Proofs' result by Razborov and
Rudich (J. CSS '97) and the pseudorandom functions by
Naor and Reingold (J. ACM '04), our results show that
{\em standard techniques for hardness amplification can
only be applied to those circuit classes for which
standard techniques cannot prove circuit lower
bounds.}\par
Our results reveal a contrast between Yao's XOR Lemma
({$ \Amp (f) := f(x_1) \oplus \ldots {} \oplus f(x_t)
\in z o $} and the Direct-Product Lemma {$ (\Amp (f) :=
f(x_1) \circ \ldots {} \circ f(x_t) \in z o^t) $}; here
{$ \Amp (f) $} is non-Boolean). Our results (1) and (2)
apply to Yao's XOR lemma, whereas known proofs of the
direct-product lemma violate both (1) and (2).\par
One of our contributions is a new technique to handle
`non-uniform' reductions, i.e. the case when {$D$}

classes of functions evolvable in his model are also
learnable in the statistical query (SQ) model of Kearns

We show that evolvability is equivalent to learnability
by a restricted form of statistical queries. Based on
this equivalence we prove that for any fixed
distribution {$D$} over the instance space, every class
of functions learnable by SQs over {$D$} is evolvable
over {$D$}. Previously, only the evolvability of
monotone conjunctions of Boolean variables over the
uniform distribution was known. On the other hand, we
prove that the answer to Valiant's question is negative
when distribution-independent evolvability is
considered. To demonstrate this, we develop a technique
for proving lower bounds on evolvability and use it to
show that decision lists and linear threshold functions
are not evolvable in a distribution-independent way.

abstract = "With our ability to sequence entire genomes, we have
for the first time the opportunity to compare the
genomes of present day species, and deduce the
trajectories by which they diversified from a common
ancestral genome. For example, starting with a small
shrew-like ancestor in the Cretaceous period about 100
million years ago, the different species of placental
mammals radiated outward, creating a stunning diversity
of forms from whales to armadillos to humans. From the
genomes of present-day species, it is possible to
computationally reconstruct what most of the DNA bases
in the genome of the common ancestor of placental
mammals must have looked like, and deduce most of the
changes that lead to humans. In so doing, we discover
how Darwinian evolution has shaped us at the molecular
level.\par
Because most random mutations to functionally important
regions of DNA reduce fitness, these changes usually
disappear over time, in a process known as negative
selection. From its unusually high conservation between
species, it is immediately evident that at least 5\% of
the human genome has been under negative selection
during most of mammalian evolution, and is hence likely
to be functionally important. Protein-coding genes and
structural RNA genes stand out among the negatively
selected regions because of their distinctive pattern
of restricted DNA base substitutions, insertions and
deletions. However, most of the DNA under negative
selection in mammalian genomes, and indeed in
vertebrate genomes in general, does not appear to be
part of protein-coding or structural RNA genes, and
shares no sequence similarity with any DNA in the
genomes of invertebrates. Experimental evidence
suggests that many of these unclassified
vertebrate-conserved DNA elements serve to regulate
genes involved in embryonic development. A significant
amount of this material appears to have been put into
place by the movement of transposons, mobile DNA
elements that are derived from ancient viruses, the
remnants of which constitute at least half of our
genome. This provides new evidence for older theories
of McClintock and later Britten and Davidson that
mobile DNA elements played a significant role in the
evolution of plant and animal gene regulatory
networks.\par
Overlaid on the background of negative selection, we
occasionally see a short segment of DNA that has
changed rapidly in a particular lineage, suggesting
possible positive selection for a modified function in
that lineage. The most dramatic example of this in the
last 5 million years of human evolution occurs in a
previously unstudied RNA gene expressed in the
developing cerebral cortex, known as Human Accelerated
Region 1 (HAR1). This gene is turned on only in a
select set of neurons, during the time in fetal
development when these neurons orchestrate the
formation of the substantially larger cortex of the
human brain. It will be many years before the biology
of such examples is fully understood, but right now we
relish the opportunity to get a first peek at the
molecular tinkering that transmuted our animal
ancestors into humans.",

models such as the best-case and worst-case partition
models [32,29]. We aim to understand whether the
hardness of a communication problem holds for almost
every allocation of the input, as opposed to holding
for perhaps just a few atypical partitions.\par
A key application is to the heavily studied data stream
model. There is a strong connection between our
communication lower bounds and lower bounds in the data
stream model that are `robust' to the ordering of the
data. That is, we prove lower bounds for when the order
of the items in the stream is chosen not adversarially
but rather uniformly (or near-uniformly) from the set
of all permutations. This random-order data stream
model has attracted recent interest, since lower bounds
here give stronger evidence for the inherent hardness
of streaming problems. Our results include the first
random-partition communication lower bounds for
problems including multi-party set disjointness and
gap-Hamming-distance. Both are tight. We also extend
and improve previous results [19,7] for a form of
pointer jumping that is relevant to the problem of

Collectively, these results yield lower bounds for a

adversarial sketch model}, unifies the well-studied
sketch and data stream models together with a
cryptographic flavor that considers the execution of
protocols in `hostile environments', and provides a
framework for studying the complexity of many tasks
involving massive data sets.\par
The adversarial sketch model consists of several
participating parties: honest parties, whose goal is to
compute a pre-determined function of their inputs, and
an adversarial party. Computation in this model
proceeds in two phases. In the first phase, the
adversarial party chooses the inputs of the honest
parties. These inputs are sets of elements taken from a
large universe, and provided to the honest parties in
an on-line manner in the form of a sequence of insert
and delete operations. Once an operation from the
sequence has been processed it is discarded and cannot
be retrieved unless explicitly stored. During this
phase the honest parties are not allowed to
communicate. Moreover, they do not share any secret
information and any public information they share is
known to the adversary in advance. In the second phase,
the honest parties engage in a protocol in order to
compute a pre-determined function of their
inputs.\par
In this paper we settle the complexity (up to
logarithmic factors) of two fundamental problems in
this model: testing whether two massive data sets are
equal, and approximating the size of their symmetric
difference. We construct explicit and efficient
protocols with sublinear sketches of essentially
optimal size, poly-logarithmic update time during the
first phase, and poly-logarithmic communication and
computation during the second phase. Our main technical
contribution is an explicit and deterministic encoding
scheme that enjoys two seemingly conflicting

abstract = "Problems of clustering data from pairwise similarity
information are ubiquitous in Computer Science.
Theoretical treatments typically view the similarity
information as ground-truth and then design algorithms
to (approximately) optimize various graph-based
objective functions. However, in most applications,
this similarity information is merely based on some
heuristic; the ground truth is really the unknown
correct clustering of the data points and the real goal
is to achieve low error on the data. In this work, we
develop a theoretical approach to clustering from this
perspective. In particular, motivated by recent work in
learning theory that asks `what natural properties of a
similarity (or kernel) function are sufficient to be
able to learn well?' we ask `what natural properties of
a similarity function are sufficient to be able to
cluster well?'\par
To study this question we develop a theoretical
framework that can be viewed as an analog of the PAC
learning model for clustering, where the object of
study, rather than being a concept class, is a class of
(concept, similarity function) pairs, or equivalently,
a property the similarity function should satisfy with
respect to the ground truth clustering. We then analyze
both algorithmic and information theoretic issues in
our model. While quite strong properties are needed if
the goal is to produce a single approximately-correct
clustering, we find that a number of reasonable
properties are sufficient under two natural
relaxations: (a) list clustering: analogous to the
notion of list-decoding, the algorithm can produce a
small list of clusterings (which a user can select
from) and (b) hierarchical clustering: the algorithm's
goal is to produce a hierarchy such that desired
clustering is some pruning of this tree (which a user
could navigate). We develop a notion of the clustering
complexity of a given property (analogous to notions of
capacity in learning theory), that characterizes its
information-theoretic usefulness for clustering. We
analyze this quantity for several natural
game-theoretic and learning-theoretic properties, as
well as design new efficient algorithms that are able
to take advantage of them. Our algorithms for
hierarchical clustering combine recent
learning-theoretic approaches with linkage-style
methods. We also show how our algorithms can be
extended to the inductive case, i.e., by using just a
constant-sized sample, as in property testing. The
analysis here uses regularity-type results of [FK] and

separate `agent' controlling each variable and an agent
is allowed to read-off the current values only of those
constraints in which it has non-zero coefficients. This
is a natural model for many distributed applications
like flow control, maximum bipartite matching, and
dominating sets.\par
The most appealing feature of our algorithms is their
simplicity and polylogarithmic convergence. For the
packing LP {$ \max \{ c x | A x = 0 \} $}, the
algorithm associates a dual variable {$ y_i = \exp [1
\epsilon * (A_i x / b_{i - 1})] $} for each constraint
$i$ and each agent $j$ iteratively increases (resp.
decreases) $ x_j $ multiplicatively if {$ A_j^T y $} is
too small (resp. large) as compared to $ c_j $. Our
algorithm starting from a feasible solution, always
maintains feasibility, and computes a $ (1 + \epsilon)
$ approximation in {$ \poly ((\ln (m n A_{\rm max}))
\epsilon) $} rounds. Here $m$ and $n$ are number of
rows and columns of {$A$} and {$ A_{\rm max} $}, also

and minimum non-zero entries {$ A_i j / (b_i c_j) $}.
Similar algorithm works for the covering LP {$ \min {by

While exponential dual variables are used in several
packing\slash covering LP algorithms before [25, 9, 13,

stateless and has polylogarithmic convergence. Our
algorithms can be thought of as applying distributed

amount of memory used. In the field of proof
complexity, the resources of time and memory correspond
to the length and space of resolution proofs. There has
been a long line of research trying to understand these
proof complexity measures, as well as relating them to
the width of proofs, i.e., the size of the largest
clause in the proof, which has been shown to be
intimately connected with both length and space. While
strong results have been proven for length and width,
our understanding of space is still quite poor. For
instance, it has remained open whether the fact that a
formula is provable in short length implies that it is
also provable in small space (which is the case for
length versus width), or whether on the contrary these
measures are completely unrelated in the sense that
short proofs can be arbitrarily complex with respect to
space.\par
In this paper, we present some evidence that the true
answer should be that the latter case holds and provide
a possible roadmap for how such an optimal separation

super-polynomial lower bounds for computing the

barriers: relativization and natural proofs. Yet over
the last decade, we have seen circuit lower bounds (for
example, that PP does not have linear-size circuits)
that overcome both barriers simultaneously. So the
question arises of whether there is a third barrier to
progress on the central questions in complexity
theory.\par
In this paper we present such a barrier, which we call
algebraic relativization or algebrization. The idea is
that, when we relativize some complexity class
inclusion, we should give the simulating machine access
not only to an oracle A, but also to a low-degree
extension of A over a finite field or ring.\par
We systematically go through basic results and open
problems in complexity theory to delineate the power of
the new algebrization barrier. First, we show that all
known non-relativizing results based on arithmetization
-- both inclusions such as IP=PSPACE and MIP=NEXP, and
separations such as MAEXP not in P/poly -- do indeed
algebrize. Second, we show that almost all of the major
open problems -- including P versus NP, P versus RP,
and NEXP versus P/poly -- will require non-algebrizing
techniques. In some cases algebrization seems to
explain exactly why progress stopped where it did: for
example, why we have superlinear circuit lower bounds
for PromiseMA but not for NP.\par
Our second set of results follows from lower bounds in
a new model of algebraic query complexity, which we
introduce in this paper and which is interesting in its
own right. Some of our lower bounds use direct
combinatorial and algebraic arguments, while others
stem from a surprising connection between our model and
communication complexity. Using this connection, we are
also able to give an MA-protocol for the Inner Product
function with {$ O(\sqrt {n} \log n) $} communication

form {$ P(x_1, \ldots {}, x_n, y) \equiv 0 $} and shows
that if {$P$} has a circuit of depth $d$ and size $s$
and if the polynomial $ f(x_1, \ldots {}, x_n) $
satisfies {$ P(x_1, \ldots {}, x_n, f(x_1, \ldots {},
x_n)) \equiv 0 $} then $f$ has a circuit of depth $ d +
3 $ and size {$ O(s \times r + m^r) $}, where $m$ is
the degree of $f$ and $r$ is the highest degree of the
variable $y$ appearing in {$P$}. In the other direction
we observe that the methods of Impagliazzo and Kabanets
imply that if we can derandomize polynomial identity
testing for bounded depth circuits then NEXP does not
have bounded depth arithmetic circuits. That is, either
NEXP $ \not \subset $ P/poly or the Permanent is not
computable by polynomial size bounded depth arithmetic
circuits.",

using two types of queries with an additive property.
Given a graph, an additive query asks the number of
edges in a set of vertices while a cross-additive query
asks the number of edges crossing between two disjoint
sets of vertices. The queries ask sum of weights for
the weighted graphs. These types of queries were
partially motivated in DNA shotgun sequencing and
linkage discovery problem of artificial
intelligence.\par
For a given unknown weighted graph {$G$} with $n$
vertices, $m$ edges, and a certain mild condition on
weights, we prove that there exists a non-adaptive
algorithm to find the edges of {$G$} using {$ O(m \log
n / \log m) $} queries of both types provided that $ m
\geq n^{\epsilon } $ for any constant $ \epsilon $ > 0.
For an unweighted graph, it is shown that the same
bound holds for all range of $m$.\par
This settles a conjecture of Grebinski [23] for finding
an unweighted graph using additive queries. We also
consider the problem of finding the Fourier
coefficients of a certain class of pseudo-Boolean
functions. A similar coin weighing problem is also
considered.",

abstract = "We study a general network design problem with
additional degree constraints. Given connectivity
requirements r$_{uv}$ for all pairs of vertices, a
Steiner network is a graph in which there are at least
r$_{uv}$ edge-disjoint paths between $u$ and $v$ for
all pairs of vertices $u$, $v$. In the MINIMUM
BOUNDED-DEGREE STEINER NETWORK problem, we are given an
undirected graph {$G$} with an edge cost for each edge,
a connectivity requirement $ r_{uv} $ for each pair of
vertices $u$ and $v$, and a degree upper bound for each
vertex $v$. The task is to find a minimum cost Steiner
network which satisfies all the degree upper
bounds.\par
The aim of this paper is to design approximation
algorithms that minimize the total cost and the degree
violation simultaneously. Our main results are the
following:\par
There is a polynomial time algorithm which returns a
Steiner forest of cost at most 2 OPT and the degree
violation at each vertex is at most 3, where OPT is the
cost of an optimal solution which satisfies all the
degree bounds.\par
There is a polynomial time algorithm which returns a
Steiner network of cost at most 2 OPT and the degree
violation at each vertex is at most $ 6 r_{\rm max} + 3
$, where OPT is the cost of an optimal solution which
satisfies all the degree bounds, and $ r_{\rm max} :=
\max_{u, v} \{ r_{u, v} \} $.\par
These results achieve the best known guarantees for
both the total cost and the degree violation
simultaneously. As corollaries, these results provide
the first additive approximation algorithms for finding
low degree subgraphs including Steiner forests,
$k$-edge-connected subgraphs, and Steiner networks. The
algorithms develop on the iterative relaxation method
applied to a natural linear programming relaxation as
in [10, 16, 22]. The new algorithms avoid paying a
multiplicative factor of two on the degree bounds even
though the algorithm can only pick edges with
fractional value $ 1 / 2 $. This is based on a stronger
characterization of the basic so-algorithm is nearly
tight.",

abstract = "We present polynomial-time approximation algorithms
for some degree-bounded directed network design
problems. Our main result is for intersecting
supermodular connectivity with degree bounds: given a
directed graph {$ G = (V, E) $} with non-negative
edge-costs, a connectivity requirement specified by an
intersecting supermodular function $f$, and upper
bounds $ a_v $, {$ b_v_{v \in V} $} on in-degrees and
out-degrees of vertices, find a minimum-cost
$f$-connected subgraph of {$G$} that satisfies the
degree bounds. We give a bicriteria approximation
algorithm that for any $ 0 \leq \epsilon \leq 1 / 2 $,
computes an $f$-connected subgraph with in-degrees at
most $ \lceil $ a_v / (1 - \epsilon) $ \rceil + 4$,
out-degrees at most $ \lceil b_v / (1 - \epsilon)
\rceil + 4 $, and cost at most $ 1 / \epsilon $ times
the optimum. This includes, as a special case, the
minimum-cost degree-bounded arborescence problem. We
also obtain similar results for the (more general)
class of crossing supermodular requirements. Our result
extends and improves the ($ 3 a_v + 4, 3 b_v + 4, 3 $
)-approximation of Lau et al. Setting $ \epsilon = 0 $,
our result gives the first purely additive guarantee
for the unweighted versions of these problems. Our
algorithm is based on rounding an LP relaxation for the
problem. We also prove that the above cost-degree
trade-off (even for the degree-bounded arborescence
problem) is optimal relative to the natural LP
relaxation. For every $ 0 < \epsilon < 1 $, we show an
instance where any arborescence with out-degrees at
most {$ b_v / (1 - \epsilon) + O(1) $} has cost at
least $ 1 - o(1) / \epsilon $ times the optimal LP
value. For the special case of finding a minimum degree
arborescence (without costs), we give a stronger $ + 2
$ additive approximation. This improves on a result of
Lau et al. [13] that gives a {$ 2 \Delta * + 2 $}
guarantee, and Klein et al. [11] that gives a {$ (1 +
\epsilon) \Delta * + O(\log_{1 + \epsilon } n) $}
bound, where {$ \Delta * $} is the degree of the
optimal arborescence. As a corollary of our result, we
(almost) settle a conjecture of Bang-Jensen et al. [1]
on low-degree arborescences. Our algorithms use the
iterative rounding technique of Jain, which was used by
Lau et al. and Singh and Lau in the context of
degree-bounded network design. It is however
non-trivial to extend these techniques to the directed
setting without incurring a multiplicative violation in
the degree bounds. This is due to the fact that known
polyhedral characterization of arborescences has the
cut-constraints which, along with degree-constraints,
are unsuitable for arguing the existence of integral
variables in a basic feasible solution. We overcome
this difficulty by enhancing the iterative rounding
steps and by means of stronger counting arguments. Our
counting technique is quite general, and it also
simplifies the proofs of many previous results. We also
apply the technique to undirected graphs. We consider
the minimum crossing spanning tree problem: given an
undirected edge-weighted graph {$G$}, edge-subsets {$
{E_i}_{i = 1}^k $}, and non-negative integers $
{b_i}_{i = 1}^k $, find a minimum-cost spanning tree
(if it exists) in {$G$} that contains at most $ b_i $
edges from each set {$ E_i $}. We obtain a $ + (r - 1)
$ additive approximation for this problem, when each
edge lies in at most $r$ sets; this considerably
improves the result of Bilo et al. A special case of
this problem is degree-bounded minimum spanning tree,
and our result gives a substantially easier proof of
the recent $ + 1 $ approximation of Singh and Lau.",
