摘要：
A kernel in a directed graph D(V, E) is a set S of vertices of D such that no two vertices in S are adjacent and for every vertex u in V \ S there is a vertex v in S such that (a, v) is an arc of D. The problem of existence of a kernel is NP-complete for a general digraph. In this paper we introduce the strong kernel problem of an undirected graph G and solve it in polynomial time for circulant graphs.
