Minesweeper generator algorithm mysql
With working numbers, a tile with number five, three mines flagged around it, and two remaining unknown tiles knows to flag all surrounding unknown tiles. For example, a tile with the number three and two flagged mines around has a working number of one: any unknown tiles around it can act as though it only needs one mine. This number I called the tile’s working number. In code, I assigned each tile the number of mines needed to satisfy its number minus the number of mines already flagged around it. If a square needs no more mines, then all unknown surrounding tiles are safe. If a square has as many empty tiles around it as it needs mines to fulfill its number, then all surrounding squares are mines. After some brainstorming, however, I came up with a rule my algorithm could apply to a board configuration to solve unknown squares.

Though the problem intrigued me, I was at a loss for how to attack it. Specifically, given a board configuration with a number of the squares identified, fill in the rest. “Mine Sweeper,” however, didn’t involve programming the game “Mine Sweeper” is kyu 1, because the task is to program an algorithm to solve Minesweeper. (Kyu, or difficulty, ranges from 1 to 8, with 8 as the easiest and 1 as the hardest.)ĭespite its ranking, I’ve always liked the idea of Minesweeper.

“Mine Sweeper” is a kyu 1 code challenge, the hardest on the site. One problem on CodeWars that caught my attention was “ Mine Sweeper” by the user myjinxin2015, a prolific creator and the second highest holder of honor, gained by solving and making the site’s code challenges.

It’s community driven, meaning that, though the problems require thinking, they are satisfying to complete.
