This paper is aimed to present the solution to vertex cover problem by means of an approximation solution. As it is NP complete problem, we can have an approximate time algorithm to solve the vertex cover problem. We will modify the algorithm to have an algorithm which can be solved in ...
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 ...

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...
A (1.35lnn+3)-approximation algorithm was obtained by Fujito [9] for MinWCVCP3 in a general graph. When k=2, the MinWCVCP2 problem is exactly the minimumweight connected vertex cover problem, for which a (ln(δmax−1)+1)-approximation follows from a classic theory on the minimum...

Divide-and-Conquer Approximation Algorithm for Vertex Cover The vertex cover problem is a classical NP-complete problem for which the best worst-case approximation ratio is $2-o(1)$. In this paper, we use a collection of simple graph transformations, each of which guarantees an approximation ra...
