Web13 sep. 2024 · 1 Answer. The answer is K 2, k: the complete bipartite graph with bipartition { X, Y } and X = 2, Y = k. Each of the bipartitions is a minimal dominating set because removing any vertex in them makes the vertex just removed neither in the dominating set or adjacent to it, the latter because the vertices in a bipartition are disjoint. WebTherefore, all that matters when searching for a minimum dominating set is their depth, gap, and size. We don't need to enumerate all possibilities for S 0, S 1; for each possible combination of depth and gap, we just need to know the minimum attainable size for a set with that depth and gap. This enables us to use dynamic programming effectively.
