这个问题有一个npo(np optimization problem)的变种,即:找到满足条件的最小顶点集,也就是使得满足条件下最小|V'|值。 首先可以看出,这是两类完全不同的问题,set cover属于集合一类问题,应用于计算机科学以及计算理论方面。vertex cover,属于图论一类问题,应用于计算机科学、计算理论、图论、数学等等方面。

Solution:SET-COVER can be seen as a generalization of VERTEX COVER.For a given graph G ,consider each vertex as a set of the edges incident upon it.Formally,we define the sets S u ={(u,v )∈E |v ∈V }for all u ∈V .Also,we take U =E and let k be the same as in ...
Vertex Cover 先来说说什么是 Vertex Cover,其实就是节点的集合,这些节点将最大地包含图里的所有边,更恰当的名字应该是 Minmum Vertex Cover,以选最少的节点来囊括所有的边。以下图为例 其中红色圈出来的节点就是 Vertex Cover。 Independent Set 再来说说 Independent Set,这也是节点的集合,一般是指 Maximum Indepen...

Set Cover is NP-complete,as it generalizes the Vertex Cover problem. (You should be able to givea polynomial-time reduction from Vertex Cover.) Therefore we try againsome greedy approximation algorithm.A natural greedy rule is to successively add sets S i to the solution, thatcover as many ...
