Vertex-cover problem is involves in two phase transitions i.e., Coverable and Uncoverable. This research work examines that several algorithms are being used to find minimum vertex cover set for different graphs. The comparison of approximation algorithm, greedy algorithm and alom's algorithm with ...
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 polynomial time and which will give near to optimum solution. It is a simple algorithm which will be based ...
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...
