简介:  Vertex Cover Problem's Link   Mean:  给你一个无向图,让你给图中的结点染色,使得:每条边的两个顶点至少有一个顶点被染色。

 Vertex Cover

Problem's Link


 

Mean: 

给你一个无向图,让你给图中的结点染色,使得:每条边的两个顶点至少有一个顶点被染色。求最少的染色顶点数。

analyse:

裸的最小点覆盖问题,二分图的最大匹配,直接套模版即可。

Time complexity: O(N^2)

   由于《Hartley, Zisserman ...》书太厚,啃不动。所以最近回头看youtube上的德国鬼子视频, 补习机器视觉最基础的知识。所以本次博文,没有算法,没有代码,纯粹的定义和识记。
