这样获得的子集中边的个数实际上就为 set cover problem 提供了一个下界:因为 vertex cover 选择的顶点必然出现在 maximum match 的边集的某条边上,这样边数不多于 vertex cover 的顶点数。 利用maximum matching 我们能获得 approximation factor 为 2 的算法:将 maximum matching 获得边集里面所有的顶点全部加入。
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。

First, we investigate organizations of Vertex-Cover solution spaces by the underlying connectivity of unfrozen vertices and provide facts on the global and local environment. Then, a Vertex-Cover Solution Number Counting Algorithm is proposed and its complexity analysis is provided, the results of ...

to optimality in polynomial time: for many of these classes, there is a PTAS for VCMS on identical machines; for bipartite graphs, however, VCMS on identical machines turns out to be APX-hard. Finally, we study the bin packing counterpart of VCMS and design a-approximation algorithm for it...
