Reconfiguring minimum dominating sets in trees
Magdalena Lemańska , Paweł Żyliński
AbstractWe provide tight bounds on the diameter of γ-graphs, which are reconfiguration graphs of the minimum dominating sets of a graph G. In particular,we prove that for any tree T of order n≥3, the diameter of its γ-graph is at most n/2 in the single vertex replacement adjacency model, whereas in the slide adjacency model, it is at most 2(n−1)/3. Our proof is constructive, leading to a simple linear-time algorithm for determining the optimal sequence of “moves” between two minimum dominatingsets ofa tree.
