• THE NUMBER OF MINIMUM CO – ISOLATED LOCATING DOMINATING SETS OF PATHS
Abstract
Let G (V, E) be a simple, finite, undirected connected graph. A non – empty set S Í V of a graph G is a dominating set, if every vertex in V – S is adjacent to atleast one vertex in S. A dominating set S Í V is called a locating dominating set, if for any two vertices v, w Î V – S, N(v) Ç S ¹ N(w) Ç S. A locating dominating set S Í V is called a co – isolated locating dominating set, if there exists atleast one isolated vertex in <V – S >. The co – isolated locating domination number gcild is the minimum cardinality of a co – isolated locating dominating set. The number of minimum co – isolated locating dominating sets in a graph G is denoted by gDcild(G). In this paper, the number gDcild is obtained for a Path Pn, where n 3.
