First we develop new properties for Vertex Cover and introduce several simple and new techniques that lead to an exact parameterized algorithm of time are then developed, which induce improvements over previously known algorithms on sparse graphs.; The dissertation concludes with discussions on some ...
For the backdoor setdetection we utilize an efficient vertex cover algorithm applied to a certain “obstruction graph” that we associate with thegiven formula. This approach gives rise to a new hardness index for formulas, the clustering-width. Our algorithm runs inuniform polynomial time on ...
Based on Max-I share degree, a heuristic algorithm is proposed. Our algorithm has two remarkable characteristics: one is that it is able to get almost the same Min-VC as that of an exact algorithm, and the approximation degree is obviously better than that of other approximation algorithms; ...

We present an algorithm which finds a minimum vertex cover in a graph G(V, E) in time O(|V|+(ak)2k3), where for connected graphs G the parameter a is defined as the minimum number of edges that must be added to a tree to produce G, and k is the maximum a over all biconnect...
At each iteration, it sets a threshold distance as a radius to see whether it is possible to cover all clients with p or less facilities within this radius (i.e., it uses this radius as Computational results In this section, we report the computational results obtained with the algorithm ...

Kernelization as heuristic structure for the vertex cover problem For solving combinatorial optimisation problems, exact methods accurately exploit the structure of the problem but are tractable only up to a certain size; approximation or heuristic methods are tractable for very large problems but may ...
Such an idea is inspired by [9], in which a 5∕3-approximation algorithm was obtained for the minimum connected vertex cover problem (MinCVC) on those classes of graphs for which MinVC is polynomial-time solvable. Besides such an idea, due to the much more complicated structure of a CVC...
