摘要
Let G = (V, E) be a connected graph. The locating-chromatic number of G, denoted by chi(L)(G), is the cardinality of a minimum locating coloring of the vertex set V(G) such that all vertices have distinct coordinates. The results on locating-chromatic number of graphs are still limited. In particular, the locating-chromatic number of trees is not completely solved. Therefore, in this paper, we study the locating-chromatic number of any binary tree. (C) 2015 The Authors. Published by Elsevier B.V.
