Abstract: The total domination game is a two-person competitive optimization game, where the players, Dominator and Staller, alternately select vertices of an isolate-free graph G. Each vertex chosen must strictly increase the number of vertices totally…

Abstract: A vertex v of a graph $$G=(V,E)$$G=(V,E) is said to ve-dominate every edge incident to v, as well as every edge adjacent to these incident edges. A set $$S \subseteq V$$S⊆V is a vertex–edge dominating…
