MINIMUM DOMINATING SETS WITH MINIMUM STATUS IN GRAPHS
A subset D of the vertex set of a graph G is said to be a dominating set if every vertex not in D is adjacent to at least one vertex in D. In this paper, we define some new concepts known as median -set of a graph and a -set with minimum status. For a dominating set D of a graph G, define the status of D as where denotes the sum of the distances from v to each vertex in D. Let be a -set of Let D be a -set such that A -set D with minimum status is known as a median -set and this is known as the dominating status of the graph G. In this paper, the concepts of a minimum dominating set with minimum status (median -set) and dominating status in a graph are defined. The median -set and dominating status of some classes of graphs are determined. Also, an algorithm for finding dominating status of a graph using distance matrix is given.
