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. For more information see the project page, the online user manual (html) or the complete manual (pdf). The barvinok package contains an iscc calculator that exposes some of the operations supported by isl.
