1.2 无向图的深度优先遍历 DFS:Depth First Search 算法思想:1、以一个未被访问过的顶点作为起始顶点,沿当前顶点的的边走向未被访问过的顶点; 2、执行1步骤后,当该分支结点都被访问后,则返回到上一个顶点,继续检索其他未被访问过的顶点,直至所有的顶点都被访问过。 即一路走到底,不破南墙不回头//这里简称直...

深度优先搜索(Depth-First Search,DFS)是一种经典的图形搜索算法,用于在图或树中遍历所有节点。它是一种递归算法,它通过深入到树或图的最深层来遍历节点,并且在回溯时继续搜索其他分支。 深度优先搜索的核心思想是递归和回溯。该算法的基本思路是从根节点开始遍历,深入到树或图的最深层,然后回溯并搜索其他分支。当...

顾名思义,BFS总是先访问完同一层的结点,然后才继续访问下一层结点,它最有用的性质是可以遍历一次就生成中心结点到所遍历结点的最短路径,这一点在求无权图的最短路径时非常有用。广度优先遍历的核心思想非常简单,用python实现起来也就十来行代码。下面就是超精简的实现,用来理解核心思想足够了: ...
