islpy is a Python wrapper around Sven Verdoolaege's `isl
<http://www.kotnet.org/~skimo/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 <http://documen.tician.de/islpy>`_.
*Requirements:* islpy needs a C++ compiler to build. GMP, which used to be
a dependency, is no longer required.
