摘要
In this paper we present unified methods to solve the minus and signed total domination problems for chordal bipartite graphs and trees in O(n(2)) and O(n + m) time, respectively. We also prove that the decision problem for the signed total domination problem on doubly chordal graphs is NP-complete. Note that bipartite permutation graphs, biconvex bipartite graphs, and convex bipartite graphs are subclasses of chordal bipartite graphs. (c) 2009 Elsevier B.V. All rights reserved.
