图的遍历(BFS+DFS第一篇文章) 关于图的搜索有两种:广度优先(bfs)深度优先 (dfs)。 以下图为例: 深度优先的基本思想简单说就是搜到底,重新搜。从v0为起点进行搜索,如果被访问过,则做一个标记,直到与v0想连通的点都被访问一遍,如果这时,仍然有点没被访问,可以从中选一个顶点,进行再一次的搜索,重复上述过程...
二叉树中的BFS方法有层序遍历,逐层开始遍历。 Input: A / \ B C / / \ D E F Output: A, B, C, D, E, F 2.DFS实现 我们以中序遍历为例,给出三种DFS实现方法! 2.1 递归实现 1)Traverse the left subtree, i.e., call Inorder(left-subtree) 2)Visit the root 3)Traverse the right subtr...

思路:还是DFS,不能用BFS,因为BFS求的是最短路径,而此题的路径不一定最短. 剪枝是关键,奇偶剪枝. 奇偶剪枝原理: 要理解奇偶剪枝,先了解一下曼哈顿距离,从一个点到达另外一个点的最短路径长度(时间)可以根据两点坐标求出, 路径长度(非最短)与最短路径的长度同奇偶,它们的差一定是偶数!举个例子,就像两个偶数...
