Abstract

We are interested in the class of vertex colored graphs which can be triangulated without the introduction of edges between vertices of the same color. This is related to a fundamental and longstanding problem for numerical taxonomists, called the Perfect Phylogeny problem. These problems are known to be polynomially equivalent and NP-Complete. In this paper we present a dynamic programming algorithm which can be used to determine whether a given vertex colored graph can be so triangulated, and which runs in O((n+m(k-2))k+1) time, where the graph has n vertices, m edges, and k colors. The corresponding algorithm for the Perfect Phylogeny Problem runs in O(rk+1kk+1+nk2) time, where n species are defined by k characters each having r states.
