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。

The proposed Map-Reduce implementation helps to run the genetic algorithm for generalized vertex cover problem (GVCP) on multiple machines parallely and computes the solution in relatively short time.doi:10.48550/arXiv.1411.7612Drona Pratap Chandu...
We present a distributed 2-approximation algorithm for the minimum vertex cover problem. The algorithm is deterministic, and it runs in \\(({\\it \\Delta}+1)^2\\) synchronous communication rounds, where \\({\\it \\Delta}\\) is the maximum degree of the graph. For \\({\\it \\De...
In this paper we describe an approximation algorihm for the vertex cover problem which has a worst case ratio Δ strictly smaller than 2 for graphs which don't have too many nodes (for example Δ≤1.9 if |V|≤1o13). Furthermore we present algorithms which improve in the case of degree...
The optimization problem is an NP-Complete problem and hence, cannot be solved in polynomial time; but what can be found in polynomial time is the near optimal solution.Vertex Cover AlgorithmThe vertex cover approximation algorithm takes an undirected graph as an input and is executed to obtain ...
Faster algorithms for 3-Path Vertex Cover were given in [2], [4], [6], [7], [10], [11]. The currently fastest algorithm for 3-Path Vertex Cover has O∗(1.713k) running time [6]. For the 4-Path Vertex Cover problem, Tu et al. gave an O∗(3k)-time algorithm [8]. ...
