We study the complexity of computing the mixed-integer hull conv(P∩(Zn×Rd)) of a polyhedron P. Given an inequality description, with one integer variable, the mixed-integer hull can have exponentially many vertices and facets in d. For n,d fixed, we give an algorithm to find the mixed-integer hull in polynomial time. Given a finite set V⊆Qn+d, with n fixed, we compute a vertex description of the mixed-integer hull of conv(V) in polynomial time and give bounds on the number of vertices of the mixed-integer hull. |
