A graph G is matching-decyclable if it has a matching M such that G - M is acyclic. Deciding whether G is matching-decyclable is an NP-complete problem even if G is 2-connected, planar, and subcubic. In this work we present results on matching-decyclability in the following classes: Hamiltonian subcubic graphs, chordal graphs, and distance-hereditary graphs. In Hamiltonian subcubic graphs we show that deciding matching-decyclability is NP-complete even if there are exactly two vertices of degree two. For chordal and distance-hereditary graphs, we present characterizations of matching-decyclability that lead to O (n)-time recognition algorithms. |
