A set D of vertices in a graph G = (V, E) is a locating-dominating set (LDS) if for every two vertices u, v of V − D the sets N (u) ∩ D and N (v) ∩ D are non-empty and different. The locating-domination number γ L (G) is the minimum cardinality of a LDS of G, and the upper locating-domination number, Γ L (G) is the maximum cardinality of a minimal LDS of G.(More)
