摘要：
A matchable set of a graph is a set of vertices joined in pairs by disjoint edges. Balas and Pulleyblank gave a linear-inequality description of the convex hull of matchable sets. We give a polynomial-time conbinatorial algorithm for the separation problem for this polytope, and a min-max theorem characterizing the maximum violation by a given point of an inequality of the system.
