abstract = "An independent set (or stable set) of a graph G ( V , E ) is a subset S of the vertices set V in which no two are adjacent. Let psi( G ) be the number of vertices in a stable set of maximum cardinality; psi( G ) is called the stability number of G . Stability numbers of a graph have been well studied, but little has been done on the number of independent subsets whose cardinality is the stability number. In this paper we will provide an algorithm to find the number of independent subsets whose cardinality is the stability number.",
