![]() So the algorithm/computition is NP-complete for a consistent boad if we analyse the complexity. After every move, the player has to estimate the risk factor of next move by measuring all the possibilities and the porbability fator of the risks. Minesweeper game, being a decision making problem based on the given constraints/obstacles, is a backtracking problem to an extent. Minesweeper algorithm and NP completeness: If the player clicks on a unsafe square which contains bomb, the game gets over. ![]() These calculations are to be performed based on multiple squares which can determine the probability of a square having bombs. This way the player needs to go ahead with calculating which square can contain the bombs. n means there are n bombs adjacent to that square. These numbers specify the number of bombs that are adjacent to that square, i.e. If the player clicks on a safe area, the square will either open up to be blank (which is mine) or will contain a number from 1 to 8. ![]() In the first step, the player has to click on a random square and just hope it's not a bomb. The goal of the player is to clear a rectangular board containing hidden "mines" or bombs without detonating any of them, with help from clues about the number of neighboring mines in each cell. Minesweeper game is all about finding the patterns and making decisions processing all the elimination chances. In this article, we're going to look at the all the rules of this game and few strategies to win against it. Minesweeper is a very popular single player strategy game. Note that it is possible to win always but it will take some time. However, there is an argument that, if the minesweeper board is already known to be consistent, solving it is only guaranteed to be co-NP-complete, and might be (or not be) NP-complete.Īnd here is the raining defending Minesweeper world rekord holder Kamil Muranski performs his skillful play.Many may think Minesweeper is a random game but it is infact a strategy game and you can win it everytime if you know the rules involved in building it and the proven strategies to play Minesweeper.įrom a computational point of view, this is an NP-Complete problem that is it will take a Computer exponential number of steps to calculate the winning move in a Minesweeper of a given size. This transforms into the fact that, in its general formulation, the minesweeper is indeed algorithmically NP-complete. This is true even for binary integer programming where variables can only be 0 or 1 rather than arbitrary integers. Unlike simple linear programming, integer programming problems are typically NP-hard. Algorithmic solutions to these problems are typically sought with the use of integer linear programming. ![]() In fact, the minesweeper is one of the classical board puzzles based on algebras of binary variables. What does all of this beautiful mathematics says to a passionate gamer? Namely, what would be a good algorithm for solving the puzzle, and is the solution computationally hard? Teytaud “Combining Myopic Optimization and Tree Search: Application to MineSweeper”.Īs for games like minesweeper in general, some of them were found to be connected with percolation theory (which is one of the most fashionable branches of probability at the moment), as well as with Markov decision processes, and computational complexity studies.Ī good example of research in this direction is a paper “The Minesweeper game: Percolation and Complexity” written by Elchanan Mossel from Microsoft Research. Some advanced studies exploring different algorithms and their relation to probabilistic models of the Minesweeper can be seen in the paper “Optimistic Heuristics for MineSweeper” by O.
