写在前面 在你观看这篇博客之前,我必须种草、安利一个讲DFS、BFS、Dijkstra的视频,非常建议想学习经典图算法的猴子去看看,时间不长但是很精辟别忘了点赞啊,链接:https://www.bilibili.com/video/av25829980?from=search&seid=12399862396157246554 回归正题 图如图所示,假设起点为
A vertex cover of a graph is a set of vertices such that each edge of the graph is incident to at least one vertex of the set. Now given a graph with several vertex sets, you are supposed to tell if each of them is a vertex cover or not. Input Specific

You are given a tree consisting exactly of n vertices. Tree is a connected undirected graph with n−1 edges. Each vertex v of this tree has a value av assigned to it. Let dist(x,y) be the distance between the vertices x and y. The distance between the

编写算法,判断一个无向图是否是一颗树。 【分析】 一个无向图G是一棵树的条件为:G必须是无回路的连通图或n-1条边的连通图,这里我们采用后者作为判断条件。例如下图所示: 上面的无向图就是一棵树,它有6个顶点,5条边。 code: #include<stdlib.h> #include<stdio.h> #include<malloc.h
At this point, we’ve sent draw calls down from our app all the way through various driver layers and the command processor; now, finally we’re actually going to do some graphics processing on it! In this part, I’ll look at the vertex pip
