Redundance of Complete Grid Graphs

Abstract

The redundance R(G) of a graph G is the minimum, over all dominating sets S, of vS(1+deg(v)), where deg(v) is the degree of vertex v. We use some dynamic programming algorithms to compute the redundance of complete grid graphs Gm,n for 1m21 and all n, and to establish good upper and lower bounds on the redundance for larger m. We conjecture that the upper bound is the redundance when m>21.
