azove

Azove is a tool designed for counting (without explicit enumeration) and enumeration of 0/1 vertices. Given a polytope by a linear relaxation or facet description P = {x | Ax <= b}, all 0/1 points lying in P can be counted or enumerated. This is done by intersecting the polytope P with the unit-hypercube [0,1] d. The integral vertices (no fractional ones) of this intersection will be enumerated. If P is a 0/1 polytope, azove solves the vertex enumeration problem. In fact it can also solve the 0/1 knapsack problem and the 0/1 subset sum problem.
