Abstract

A set of vertices W locallyresolves a graph G if every pair of adjacent vertices is uniquely determined by its coordinate of distances to the vertices in W. The minimum cardinality of a local resolving set of G is called the localmetricdimension of G. A graph G is called a k-regular graph if every vertex of G is adjacent to k other vertices of G. In this paper, we determine the local metric dimension of an (n3)-regular graph G of order n, where n5.
