Complexity of Chess Domination Problems
share
We study different domination problems of attacking and non-attacking rooks and queens on polyominoes and polycubes of all dimensions. Our main result proves that the problem is NP-complete for non-attacking queens on polyominoes and for non-attacking rooks on three-dimensional polycubes. We also analyze these problems on the set of convex polyominoes, for which we conjecture and give some evidence that these domination problems restricted to this subset of polyominoes might be NP-complete for both, queens and rooks. We have also computed new values for classical queen domination problems on chessboards (square polyominoes). For our computations, we have translated the problem into an integer linear programming instance. Finally, using this computational implementation and the game engine Godot, we have developed a video game of minimal domination of queens and rooks on randomly generated polyominoes.
