摘要：

We consider the problem of finding a transitive orientation of a comparability graph, such that the edge set of its covering graph contains a given subset of edges. We propose a solution which employs the classical technique of modular tree decomposition. The method leads to a polynomial time algorithm to construct such, an orientation or report that it does not exist. (c) 2006 Elsevier B.V. All rights reserved.
