- Description
- Let G=(V,A) be a directed graph, and let S⊆V be a set of vertices. Let the sequence S=S0⊆S1⊆S2⊆⋯ be defined as follows: S1 is obtained from S0 by adding all out-neighbors of vertices in S0. For k⩾2, Sk is obtained from Sk−1 by adding all vertices w such that for some vertex v∈Sk−1, w is the unique out-neighbor of v in V∖Sk−1. We set M(S)=S0∪S1∪⋯, and call S a power dominating set for G if M(S)=V(G). The minimum cardinality of such a set is called the power domination number of G. In this paper, we determine the power domination numbers of de Bruijn and Kautz digraphs.
