abstract = "This paper presents a series of new algorithms for
reliably graphing two-dimensional implicit equations
and inequalities. A clear standard for interpreting the
graphs generated by two-dimensional graphing software
is introduced and used to evaluate the presented
algorithms. The first approach presented uses a
standard interval arithmetic library. This approach is
shown to be faulty; an analysis of the failure reveals
a limitation of standard interval arithmetic.
Subsequent algorithms are developed in parallel with
improvements and extensions to the interval arithmetic
used by the graphing algorithms. Graphs exhibiting a
variety of mathematical and artistic phenomena are
shown to be graphed correctly by the presented
algorithms. A brief comparison of the final algorithm
presented to other graphing algorithms is included.",
