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 parameterized by the solution size k is the quintessential fixed-parameter tractable problem. FPT algorithms are most interesting when the parameter is small. Several lower bounds on k are well-known, such as the maximum size of a matching. This has led to a line of research on...
PAT-1134 Vertex Cover (图的建立 + set容器) A vertex cover of a graph is a set of vertices such that each edge of the graph is incident to at least one vertex of the set. Now given a graph with several vertex sets, you are supposed to tell if each of them is a vertex cover or...
