摘要：
The equipartition problem is defined as follows: given a graph G = (V, E) and edge weights ce, partition the set V into two sets of ⌈1/2|V|⌉ and ⌊1/2|V|⌋ nodes in such a way that the sum of the weights of edges not having both endnodes in the same set is maximized or minimized. An equicut is a feasible solution of the above problem and the equicut polytope Q(G) is the convex hull of the incidence vectors of equicuts in G. In this paper we describe some facet inducing inequalities of this polytope. © 1990 The Mathematical Programming Society, Inc.
