1 广度优先搜索算法(Breadth-First_Search) 核心思想是,从起始节点开始,将它的所有Neigbors加入到下一步要搜索的预备队列中; 然后从预备队列按一定规则选出一个节点,重复上一步骤;直到找到目的节点。 1.1涉及到的数据结构 Graph: 有向图,每个节点可以指向的下一个临近节点组成一个列表; 数组: 存放待遍历的节点,常...

A*(A-Star)算法,典型的启发式搜索算法。是带有评估函数的优先队列式广度优先搜索算法;是一种静态路网中求解最短路径最有效的直接搜索方法,也是解决许多搜索问题的有效算法。 A*算法使用优先队列存储当前状态下可选择的所有后续状态,优先队列的优先策略由评估函数决定,即每次从优先队列中选择出估计值最少的状态。启发...
