Abstract

A distance-Hereditary graph G has a binary tree representation called a decomposition tree. Given a decomposition tree, many graph-theoretical problems can be efficiently solved on G using the binary tree contraction technique. In this paper, we present an algorithm to construct a decomposition tree in O(log2 n) time using O(n+m) processors on a CREW PRAM, where n and m are the number of vertices and edges of G, respectively.
