Given a graph, a dominating set is a subset D of nodes such that each node in the graph is either in D, … The set cover problem is a well-known NP-hard problem – the decision version of set covering was one of Karp's 21 NP-complete problems. There exist a pair of polynomial-time L-reductions between the minimum dominating set problem and the set cover problem. These reductions (see below) show that an efficient algorithm for the minimum dominating set problem would provide an efficient algorithm for the set cover problem, and vice versa. Moreover, the reductions preserve … Web1 dec. 2016 · Domination in graphs has been an extensively researched branch of graph theory.
