INTRODUCTION In this paper we give a survey of the results related to the strong metric dimension of graphs. The strong metric dimension (SMD) is a recently introduced graph invariant [11], connected to well known metric dimension [1,12] that has been widely investigated. Metric dimension of a graph can be defined as follows. Let G be a simple connected undirected graph G = (V, E), where V is a set of vertices, and E is a set of edges. The distance between vertices u and v, . the length of a shortest u-v path is denoted by d(u,v). A vertex x of the graph G resolves two vertices u and v of G if d(x,u) ≠ d(x,v). An ordered vertex set S = {x1, ., xk} is a resolving set of G if for every two distinct vertices of G there exists a vertex of S which .
