Abstract:SYNOPTIC ABSTRACTThe minimum cost perfect 2-matching problem is defined on a weighted undirected graph Q = (V,t',c) and is the problem of finding a minimum weight subset of edges £ ~ £ such that each vertex is incident to exactly two edges in £. The problem appears as a relaxation subproblem in routing environments where the distance matrices are symmetric. This paper presents a multiplier adjustment approach for obtaining a quick lower bound on the linear programming relaxation of the minimum cost perfect 2-… Show more
