pycddlib is a Python wrapper for Komei Fukuda's cddlib.

cddlib is an implementation of the Double Description Method of Motzkin et al. for generating all vertices (i.e. extreme points) and extreme rays of a general convex polyhedron given by a system of linear inequalities.

The program also supports the reverse operation (i.e. convex hull computation). This means that one can move back and forth between an inequality representation and a generator (i.e. vertex and ray) representation of a polyhedron with cdd. Also, it can solve a linear programming problem, i.e. a problem of maximizing and minimizing a linear function over a polyhedron.
