Single-Player and Two-Player Buttons & Scissors Games


الملخص بالإنكليزية

We study the computational complexity of the Buttons & Scissors game and obtain sharp thresholds with respect to several parameters. Specifically we show that the game is NP-complete for $C = 2$ colors but polytime solvable for $C = 1$. Similarly the game is NP-complete if every color is used by at most $F = 4$ buttons but polytime solvable for $F leq 3$. We also consider restrictions on the board size, cut directions, and cut sizes. Finally, we introduce several natural two-play
