A Roman dominating function of a graph G is a function f : V โ {0, 1, 2} such that every vertex with 0 has a neighbor with 2. The minimum of f (V (G)) = vโV f (v) over all such functions is called the Roman domination number ฮณ R (G). A 2-rainbow dominating function of a graph G is a function g that
This paper presents a (10 + ε)-approximation algorithm to compute minimum-weight connected dominating set (MWCDS) in unit disk graph. MWCDS is to select a vertex subset with minimum weight for a given unit disk graph, such that each vertex of the graph is contained in this subset or has a neigh
