Computational Complexity of Minesweeper Variants: Consistency, Inference, and Solvability

Q: What other variants or generalizations of Minesweeper could be analyzed using the graph orientation framework developed in this paper

The graph orientation framework developed in the paper can be applied to analyze various variants or generalizations of Minesweeper. Some potential options include: Different Board Sizes: The framework can be used to analyze Minesweeper games with larger or smaller board sizes. By adjusting the number of cells and clues, the complexity of consistency, inference, and solvability can be studied in different settings. Different Mine Distributions: Variants where mines are distributed in unique patterns or densities can be explored. This could involve clustering mines in certain areas or spreading them out evenly across the board, affecting the difficulty of the game. Additional Game Elements: Introducing new elements such as power-ups, obstacles, or special cells that impact gameplay could be analyzed using the framework. These elements could add complexity to the game and require new strategies for solving. Multiplayer Minesweeper: Analyzing Minesweeper games where multiple players interact on the same board, potentially revealing information to each other or competing to clear cells, could be an interesting application of the framework. 3D Minesweeper: Extending the framework to analyze Minesweeper games in a three-dimensional space, with mines and clues distributed across multiple layers, could provide insights into the complexity of solving puzzles in a 3D environment.

Kernekoncepter

The computational complexity of three key decision problems related to the popular game Minesweeper is analyzed: consistency (determining if a set of clues has a valid mine arrangement), inference (determining if a cell can be proven safe), and solvability (determining if a player can win the game by safely clicking all non-mine cells).

Resumé

The paper studies the computational complexity of three decision problems related to the popular game Minesweeper:

Consistency: Given a set of clues, is there any arrangement of mines that satisfies it? This problem has been known to be NP-complete since 2000.
Inference: Given a set of clues, is there any cell that the player can prove is safe? The coNP-completeness of this problem has been in the literature since 2011, but the authors discovered a flaw in the existing proofs and provide a fixed proof.
Solvability: Given the full state of a Minesweeper game, can the player win the game by safely clicking all non-mine cells? This problem has not yet been studied, and the authors prove that it is coNP-complete.

The authors develop a framework based on graph orientation to prove the hardness results. They define three related graph orientation decision problems (consistency, promise-inference, and uniqueness) and show that each is hard using a particular set of simple abstract gadgets. They then apply this framework to Minesweeper and many variants, showing that finding well-behaved constructions in Minesweeper that behave like the abstract gadgets is enough to prove hardness for all three Minesweeper problems.
