We show that recognition of the class of strip graphs is .-complete even if all intervals are of length 2. Strip graphs are important to the study of job selection, where we need an equivalence relation to connect multiple int

In this paper we focus on the first part of such an approach . the computation of the probability vectors for the random walks, and propose a more efficient algorithm for computing these vectors in time complexity that is linear i

Michel Chrétien,Kenneth W. McKernsal comparability graphs are comparability graphs of posets of dimension four. Among other uses, this gives an implicit representation of a chordal comparability graph using .(.) integers so that, given two vertices, it can be determined in .(1) time whether they are adjacent, no matter how dense the

The .-branches are, just as the .-trees, a subclass of the chordal graphs where all minimal separators have size .. However, a striking difference arises when considering s
