The connected domination game is played just as the game, with an additional requirement that at each stage of vertices induce a subgraph. number moves in D-game (an S-game, resp.) on graph G when both players play optimally denoted by $$\gamma _\mathrm{cg}(G)$$ ( _\mathrm{cg}'(G)$$ , resp.). Connected Game Continuation Principle established substitute for classical which does not hold game. Le...
