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。

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 ...
