Integer Set Library
isl is a library for manipulating sets and relations of integer points
bounded by linear constraints. Supported operations on sets include
intersection, union, set difference, emptiness check, convex hull,
(integer) affine hull, integer projection, computing the lexicographic
minimum using parametric integer programming, coalescing and
parametric vertex enumeration. It also includes an ILP
solver based on generalized basis reduction, transitive closures
on maps (which may encode infinite graphs), dependence analysis and
bounds on piecewise step-polynomials.
