Abstract: Given a transitive orientation G → of a comparability graph G, a vertex of G is a source (sink) if it has indegree (outdegree) zero in G →, respectively. A source set of G is a subset of vertices formed by sources of some transitive orientation G →. A pair of subsets S,T⊆V(G) is a source-sink pair of G when the vertices of S and T are sources and sinks, of some transitive orientation G →, respectively. We describe algorithms for finding a transitive orientation with a maximum source-sink pair in a comparability graph. The algorithms are applications of modular decomposition and are all of linear-time complexity. © 2002 Elsevier Science B.V.
