GitHub代码 https:///while-TuRe/A-star-ShortestPath(用vscode即可运行) 算法思路 开始搜索(Starting the Search) 一旦我们把搜寻区域简化为一组可以量化的节点后,就像上面做的一样,我们下一步要做的便是查找最短路径。在 A* 中,我们从起点开始,检查其相邻的方格,然后向四周扩展,直至找到目标。 我们这样开始我...

在A*的主循环中,OPEN集保存所有需要检查的结点。Beam Search是A*算法的一个变种,这种算法限定了OPEN集的尺寸。如果OPEN集变得过大,那些没有机会通向一条好的路径的结点将被抛弃。缺点是你必须让排序你的集合以实现这个,这限制了可供选择的数据结构。

A*(念做:A Star)算法是一种很常用的路径查找和图形遍历算法。它有较好的性能和准确度。本文在讲解算法的同时也会提供Python语言的代码实现,并会借助matplotlib库动态的展示算法的运算过程。 A*算法最初发表于1968年,由Stanford研究院的Peter Hart, Nils Nilsson以及Bertram Raphael发表。它可以被认为是Dijkstra算法的...
