Solving the sliding puzzle using a basic AI algorithm. Let’s start with what I mean by an “8-Puzzle” problem. N-Puzzle or sliding puzzle is a popular puzzle that consists of N tiles where N can be 8, 15, 24, and so on. In our example N = 8. The puzzle is divided into ...
8-puzzles can be solved by using the path searching algorithms such as Best-first search, Depth-fist search, Dijkstra's algorithm, or the A* algorithm. In this paper, the A* algorithm will be the one chosen. The A* algorithm is known to be an improvement to the Dijkstra's algorithm ...
【原】八数码问题(8-puzzle Problem) 问题描述: 有一个3×3的棋盘,其中有0~8九个数字,0表示空格,其他的数字可以和0交换位置。求由初始状态到达目标状态步数最少的解。 解决八数码问题的常用方法为图搜索法,可用广度优先、深度优先和A*算法实现,其中A*算法又因估价函数的不同而有着不同的搜索时间。 程序说明...

接下来可以利用 A* search algorithm 来解决这个问题:先把初始 State 加入优先队列,然后每次删去 Manhattan 最小的 State,加入其相邻的 State(如果该 State 不曾在优先队列中出现过),直至删去的 State 的 Manhattan 距离为 0。 注意到,任意给定一个初始状态,未必能达到目标状态。可以利用逆序数来判断:当且仅当原...
