摘要

This paper deals with the stable b-matching problem in multigraphs, called the stable multiple activities problem, SMA for short. In an SMA instance a multigraph G = (V, E), capacity b(v) and a linear order <(v) on the set of edges incident to v, for each vertex v is an element of V are given. A stable b-matching is sought, i.e. a set of edges M such that each vertex v is incident with at most b(v) edges and for each edge e is not an element of M a vertex v incident with e and b(v) distinct edges f(1),...,f(b(v)) incident to v exist in M, all of them <(v)-smaller than e. We show how to decrease the computational complexity of the SMA algorithm to run in O(vertical bar E vertical bar) time and derive some properties of stable b-matchings. (C) 2007 Elsevier B.V.
