The Minimum Vertex Cover Problem Adleman-Lipton ModelNP-Complete ProblemThe minimum vertex cover (MVC) problem is a vitally important NP-complete problem in graph theory and applied mathematics. In this paper, we present a DNA algorithm for solving the MVC problem with DNA molecular ope...
The vertex cover problem is one of the six "basic" NP-complete problems according to Garey and Johnson[ 4 ]. Therefore, the problem cannot be solved in polynomial time unless P \\( { = } \\) NP. However, the NP-completeness of the problem does not obviate the need for solving it ...
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 minimum weighted vertex cover (MWVC) problem, an extension of the classical minimum vertex cover (MVC) problem, is an important NP-complete combinatorial optimization problem with a wide range of applications. The objective of this paper is to design an efficient local search algorithm to sol...

This optimal vertexcover is the optimization version of an NP-complete problem. However, it is not too hard to find a vertex-cover that is near optimal.APPROX-VERTEX_COVER (G: Graph) c ← { } E' ← E[G] while E' is not empty do Let (u, v) be an arbitrary edge of E' c ...
Graph vertex-covering problem is a NP-complete problem. 图的顶点覆盖问题是一个困难的NP-完全问题,并且有许多良好的应用。5) Min-VC 最小点覆盖问题 1. The Parameterized Vertex Cover Problem (short as PVC or VC) and the Minimum Vertex Cover Problem (short as Min-VC) are two important NP-...
The vertex-disjoint triangles (VDT) problem asks for a set of maximum number of pairwise vertex-disjoint triangles in a given graph G. The triangle cover problem asks for the existence of a perfect triangle packing in a graph G. It is known that the triangle cover problem is NP-complete ...
