首先定义了open表、closed表,声明了Point类,定义了初始节点init(2, 0, 3, 1, 8, 4, 7, 6, 5)和目的节点(1, 2, 3, 8, 4, 5, 0, 7, 6)。 在开始进行A_star(A*)算法之前,先定义几个函数: 1) getKey:找出Point节点中0(即空格)的位置索引; 2) up:空格上移函数。把某节点的空格和上方位...

A-star (also referred to as A*) is one of the most successful search algorithms to find the shortest path between nodes or graphs. It is an informed search algorithm, as it uses information about path cost and also uses heuristics to find the solution. In this article, I will focus on...
A*搜索算法(A Star Search Algorithm) A*算法主要用于在二维平面上寻找两个点之间的最短路径。在从起始点到目标点的过程中有很多个状态空间,DFS和BFS没有任何启发策略所以穷举所有的状 态空间,不适合仅需对局部进行搜索的应用。启发式搜索的关键在于:当前节点在选择下一步节点的时候,可以通过一个启发函数进行选择...
