Version numbers for these %%% files begin at 2.00. %%% %%% Volumes from the 1990s average more than 200 %%% articles yearly, so a complete bibliography %%% for this journal could contain more than 6000 %%% entries from 1958 to 2000. %%% %%% These bibliographies also include ACM %%% Algorithms 1--492. For Algorithms 493--686, %%% including Algorithm 568, published in ACM %%% Transactions on Programming Languages and %%% Systems (TOPLAS), see the companion %%% bibliographies, toms.bib and toplas.bib. %%% %%% All published Remarks and Corrigenda are %%% cross-referenced in both directions, so %%% that citing a paper will automatically %%% generate citations for those Remarks and %%% Corrigenda. Cross-referenced entries are %%% duplicated in cacm19*.bib and toms.bib, so %%% that each is completely self-contained. %%% %%% Source code for ACM Algorithms from 380 %%% onwards, with some omissions, is available %%% via the Netlib service at %%% http://netlib.ornl.gov/, and %%% ftp://netlib.bell-labs.com/netlib/toms. %%% %%% There is a World Wide Web search facility %%% for articles published in this journal from %%% 1959 to 1979 at %%% http://ciir.cs.umass.edu/cgi-bin/web_query_form/public/cacm2.1. %%% %%% The initial draft of entries for 1981 -- %%% 1990 was extracted from the ACM Computing %%% Archive CD ROM for the 1980s, with manual %%% corrections and additions. Additions were %%% then made from all of the bibliographies in %%% the TeX User Group collection, from %%% bibliographies in the author's personal %%% files, from the Compendex database %%% (1970--1979), from the IEEE INSPEC database %%% (1970--1979), from tables of contents %%% information at http://www.acm.org/pubs/cacm/, %%% from Zentralblatt fur Mathematik Mathematics %%% Abstracts at %%% http://www.emis.de/cgi-bin/MATH/, from %%% bibliographies at Internet host %%% netlib.bell-labs.com, and from the computer %%% science bibliography collection on %%% ftp.ira.uka.de in /pub/bibliography to which %%% many people of have contributed.

Citation tags were automatically %%% generated by software developed for the %%% BibNet Project. %%% %%% In this bibliography, entries are sorted in %%% publication order within each journal, %%% using bibsort -byvolume. %%% %%% The checksum field above contains a CRC-16 %%% checksum as the first value, followed by the %%% equivalent of the standard UNIX wc (word %%% count) utility output of lines, words, and %%% characters.

The paradigm problem considered is that of testing a series of messages one-by-one for membership in a given set of messages. Two new hash-coding methods are examined and compared with a particular conventional hash-coding method. The computational factors considered are the size of the hash area (space), the time required to identify a message as a nonmember of the given set (reject time), and an allowable error frequency. The new methods are intended to reduce the amount of space required to contain the hash-coded information from that associated with conventional methods. The reduction in space is accomplished by exploiting the possibility that a small fraction of errors of commission may be tolerable in some applications, in particular, applications in which a large amount of data is involved and a core resident hash area is consequently not feasible using conventional methods.

Generations of cryptanalysts have expended untold man-years, thus far without success, attempting tode code them; vast armies of fortune hunters and treasure seekers have devoted Herculean labors to digging up the rolling hills of Virginia trying to locate the promised bonanza. \par The history of pertinent activities would fill volumes, yet serious students of cryptography have always had nagging doubts about the cyphers' authenticity. It has been alleged that the ``known solution'' to Cypher Number Two: 115, 73, 24, 818, 37, 52, 49, \ldots{} (``I have deposited in the County of Bedford about four miles from Buford's in an excavation or vault \ldots{}'') with the aid of an unsanitized version of the Declaration of Independence was merely a superb, imaginative, and grandiose hoax perpetrated ages ago for whatever reasons. Modern computer technology could obviously perform signature analyses the process of encoding itself so as to yield new clues and deeper insights into their construction. For the benefit of the uninitiated, the encoding method used in the second cypher employs a specified document whose words are simply numbered consecutively, and first letters of these words are sought out at random to match the letters of these words are sought out at random to match the letters of the clear text or message. \par The sequence of numbers corresponding to these matches is then written down as the final code. While primitive, the process has the advantage of relative security until the source document becomes known; at that moment the cypher can be decoded even by second graders. The work now completed with the help of our UNIVAC 1108 includes numerous analytical studies of the Beale cyphers and various types of simulations. \par For example, we have turned the entire process of simulated encoding by various schemes over to the machine and analyzed the signatures of these synthetic codes; we have also encoded various messages by hand, using different texts and a variety of methods to obtain their signatures. These simulations provide convincing evidence that the signatures are both process and data dependent; they indicate also very strongly that Mr. Beale's cyphers are for real and that it is merely a matter of time before someone finds the correct source document and locates the right vault in the common-wealth of Virginia.", acknowledgement = ack-nhfb, classcodes = "B6120B (Codes); C6130 (Data handling techniques)", journal-URL = "https://dl.acm.org/loi/cacm", keywords = "Beale Cyphers codes; codes; computer applications; computer signature simulation; cryptanalysis; cyphers; Declaration of Independence; decoding; encoding; Magna Carta; numerical cryptographic codes; pseudotext; results analysis; signature; simulation; Thomas Jefferson Beale; treasure site identification", oldlabel = "Hammer71", treatment = "A Application", XMLdata = "ftp://ftp.informatik.uni-trier.de/pub/users/Ley/bib/records.tar.gz#journals/cacm/Hammer71", } @Article{Klinger:1971:PWG, author = "Allen Klinger", title = "Pattern Width at a Given Angle", journal = j-CACM, volume = "14", number = "1", pages = "15--20", month = jan, year = "1971", CODEN = "CACMA2", ISSN = "0001-0782 (print), 1557-7317 (electronic)", ISSN-L = "0001-0782", bibdate = "Mon Jan 22 06:55:12 MST 2001", bibsource = "http://dblp.uni-trier.de/db/journals/cacm/cacm14.html#Klinger71; https://www.math.utah.edu/pub/tex/bib/cacm1970.bib", acknowledgement = ack-nhfb, classcodes = "B6140C (Optical information, image and video signal processing); C1250 (Pattern recognition)", corpsource = "Univ.

MULTIPLE's proving program (PP) uses two evaluation functions to guide its search for a proof of whether or not a particular goal is achievable. Thirteen general features of predicate calculus clauses were created for use in the automatic learning of better evaluation functions for PP. A multiple regression program was used to produce optimal coefficients for linear polynomial functions in terms of the features.\par Also, automatic data-handling routines were written for passing data between the learning program and the proving program, and for analyzing and summarizing results. Data was generally collected for learning (regression analysis) from the experience of PP. A number of experiments were performed to test the effectiveness and generality of the learning program. Results showed that the learning produced dramatic improvements in the solutions to problems which were in the same domain as those used for collection learning data.

In particular, subexpressions should be executed in order of decreasing memory and processor time requirements. This observation is valid for configurations ranging from a uniprocessor with an unbuffered main memory to multiprocessor with a ``cache'' buffer memory.

This requires that the compiler repair errors encountered during both translation and execution, and the design of PL/C is dominated by this consideration. PL/C also introduces several explicit user-controlled facilities for program testing. To accommodate these extensions to PL/I without abandoning compatibility with the IBM compiler, PL/C permits ``pseudo comments'' --- constructions whose contents can optionally be considered either source text or comment.
