摘要
A connected matching M in a graph G is a matching such that every pair of edges of M is joined by an edge of G. Plummer, Stiebitz and Toft introduced connected matchings in connection with their study of the famous Hadwiger Conjecture. In this paper, I prove that the connected matching problem is NP-complete for 0-1-weighted bipartite graphs, but polytime-solvable for chordal graphs and for graphs with no circuits of size 4.
