Abstract

A graph G = (V, E) is called a probe graph of graph class G if V can be partitioned into two sets P (probes) and N (nonprobes), where N is an independent set, such that G can be embedded into a graph of G by adding edges between certain nonprobes. A graph is distance hereditary if the distance between any two vertices remains the same in every connected induced subgraph. Distance-hereditary graphs have been studied by many researchers. In this paper we give an O(nm)-time algorithm for recognizing probe graphs of distance-hereditary graphs.
