Web6 mrt. 2004 · Abstract. A Roman dominating function on a graph G = ( V, E) is a function f: V→ {0,1,2} satisfying the condition that every vertex u for which f ( )=0 is adjacent to at least one vertex for which f ( )=2. The weight of a Roman dominating function is the value f ( V )=∑ V ( ). The minimum weight of a Roman dominating function on a graph.
