This approach uses the graph representing the vertex covering problem as the connectionist network without any modifications (nodes of the connectionist network represent vertices and links represent edges of the given graph). The activation rule governing node behavior is derived by breaking down the ...
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。
scientists.This paper mainly studies two variants of the vertex covering problem.One is the connected vertex covering problem and the other is the weighted tree covering problem.The paper gives the fixed parameter tractable algorithm for these problems,respectively,and it is the best results for the...

A linear time approximation algorithm for the weighted set-covering problem is presented. For the special case of the weighted vertex cover problem it produces a solution of weight which is at most twice the weight of an optimal solution.
Given a family of subsets S = {S1, . . . , Sm} over a set of elements X = {x1, . . . , xn} and an integer p, max k-set cover consists of finding a set T of at most k subsets covering at least p elements. This problem, when parameterized ... E Bonnet,V Paschos,F Si...
