1.去GraphVis官网下载对应的js,新版和旧版的js有所不同,看自己需求引入旧版还是新版(GraphVis官方网址:http://www.graphvis.cn/) visgraph.min.js (基本配置js) visgraph-layout.min.js(配置布局js) 2.在需要的vue文件引入js文件 import VisGraph from '@/assets/js/GraphVis/old/visgraph.min.js' // 自己对应的js文件位置 import Layo

这个双12,别人都在抢红包.逛淘宝.上京东,我选择再续我的“漫谈可视化”系列(好了,不装了,其实是郎中羞涩...) 上篇<漫谈可视化Prefuse(三)---Prefuse API数据结构阅读有感>主要介绍了可视化工具Prefuse API中主要解读的是prefuse.data包中的主要接口,并利用<漫谈可视化Prefuse(一)---从SQL Server数据库读取数据>中例子,将参数配置模块剥离出来,实现界面传值,绘制图形. 本篇决定不再贴API,实在没啥意思,还占篇幅(但是不

题目: http://poj.org/problem?id=1129 开始没读懂题,看discuss的做法,都是循环枚举的,很麻烦.然后我就决定dfs,调试了半天终于0ms A了. #include <stdio.h> #include <string.h> ][], vis[][]; int n, ans; void calc() { ; ; i < ; i++) { ; j < n; j++) { if(vis[j][i]) { cnt++; break; } }

题目链接: http://poj.org/problem?id=3687 要逆向建图,输入的时候要判重边,找入度为0的点的时候要从大到小循环,尽量让编号大的先入栈,输出的时候注意按编号的顺序输出重量,不是按重量大小输出编号.. 题目确实很简单,但是感觉很经典. #include <stdio.h> #include <string.h> #include <stack> using namespace std; ][], vis[]; ], weight[]; stac

此部分是计算机视觉部分,主要侧重在底层特征提取,视频分析,跟踪,目标检测和识别方面等方面.对于自己不太熟悉的领域比如摄像机标定和立体视觉,仅仅列出上google上引用次数比较多的文献.有一些刚刚出版的文章,个人非常喜欢,也列出来了. 33. SIFT关于SIFT,实在不需要介绍太多,一万多次的引用已经说明问题了.SURF和PCA-SIFT也是属于这个系列.后面列出了几篇跟SIFT有关的问题.[1999 ICCV] Object recognition from local scale-invar

又是虚脱的一天啊QAQ,早上习惯性迟到,九点多到学校开始码题,六道题看下来花了将近一个小时,主要纠结于第二题和第六题.到了十点,没再深入思考,开始码题.. 一直到十一点半,写了两道题.然后吃完饭后中午把剩下会的两道题水了水就开始去主攻第六题,第二题感觉不是很有思路. 然后就从三点想到四点,中间考量了很多算法好像都不行,但我能确定这是一道最短路的计数问题,相关的题目之前做过一道,但是面对这道题还不是很有想法.无奈,最后码了暴力走人. 今天没精力再改题了,一会还要补文化课的作业,具体的题解和小结什么

题目传送门 /* 二分图点染色:这题就是将点分成两个集合就可以了,点染色用dfs做, 剩下的点放到点少的集合里去 官方解答:首先二分图可以分成两类点X和Y, 完全二分图的边数就是|X|*|Y|.我们的目的是max{|X|*|Y|}, 并且|X|+|Y|=n. 修正:实现多连通块染色,然后贪心选择,将两个集合个数差大的连通块优先添加,能尽量使得un*vn最大 */ #include <cstdio> #include <algorithm> #include <cstring&

Given a Directed Graph and two vertices in it, check whether there is a path from the first given vertex to second. For example, in the following graph, there is a path from vertex 1 to 3. As another example, there is no path from 3 to 0. We can eith
