Abstract


A graph G = (V,E) is well-covered if each maximal independent set of G is maximum. A graph G = (V,E) is split if there is a partition V = (S,K), where S is an independent set and K is a clique. A well-covered split graph is at a same time well-covered and split. Given a class C of graphs, a graph G = (V,E) is C−probe if there is a partition for V = (N,P) into probes P and non-probes N, where N is an independent set and new edges may be added between non-probes such that the resulting graph is in the graph class C. We say that (N,P) is a C probe partition for G. The C−PARTITIONED PROBE problem consists of an input graph G and a probe partition V = (N,P) and the question: Is (N,P) a C−probe partition? In this paper we consider C the class of well-covered split graphs, and we prove that C−PARTITIONED PROBE problem belong to the polynomial problem class P.
