Wrapper around isl, an integer set library

Project description

https://badge.fury.io/py/islpy.png

islpy is a Python wrapper around Sven Verdoolaege’s isl, 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.

Islpy comes with comprehensive documentation.

Requirements: islpy needs a C++ compiler to build. GMP, which used to be a dependency, is no longer required.
