Abstract:
Evolutionary multiobjective optimization for the classical vertex cover problem has been analysed in Kratsch and Neumann ( 2013 ) in the context of parameterized complexity analysis. This article extends the analysis to the weighted vertex cover problem in which integer weights are assigned to the vertices and the goal is to find a vertex cover of minimum weight. Using an alternative mutation operator introduced in Kratsch and Neumann ( 2013 ), we provide a fixed parameter evolutionary algorithm with respect to [Formula: see text], the cost of an optimal solution for the problem. Moreover, we

Abstract:
This paper considers a bipartite graph where a perfect matching does not necessarily exist. Linear programming is used in this paper as a special case of the linear program is the assignment problem, which is another name for the weighted maximum matching problem. The objective is to show that linear programming, in particular the simplex algorithm, can be used to calculate maximum weight matchings and minimum weighted vertex covers. This study also calculates and shows the equivalence of the maximum matching and minimum vertex cover cardinalities, and uses linear programming duality to presen

Abstract:
We have designed di erent heuristics for both searching on Massive graphs and regularizing Deep Neural Networks in this work. Both the problem of nding a minimum vertex cover (MinVC) and the maximum edge weight clique (MEWC) in a graph are prominent NP-hard problems of great importance in both theory and application. During recent decades, there has been much interest in nding optimal or near-optimal solutions to these two problems. Many existing heuristic algorithms for MinVC are based on local search strategies. An algorithm called FastVC takes a rst step towards solving the MinVC problem

We show that given G, B and a weight function w:V→Z^+, a minimum B-skip vertex cover of weight at most ⌈log_2⁡〖|V|〗 ⌉, if it exists, can be found in polynomial time. Our result and proof generalize those of Papadimitriou and Yannakakis.

The cardinality of a minimum k-path vertex cover is called the k-path vertex cover number of a graph G. In this thesis, we consider the weighted version of a k-path vertex cover problem, in which vertices are given weights, and propose an O(n3) algorithm for solving this problem in cactus graphs.

Abstract:
The minimum weight vertex cover (MWVC) problem is an important combinatorial optimization problem with various real-world applications. Due to its NP hardness, most works on solving MWVC focus on heuristic algorithms that can return a good quality solution in reasonable time. In this work, we propose two dynamic strategies that adjust the behavior of the algorithm during search, which are used to improve a state of the art local search for MWVC named FastWVC, resulting in two local search algorithms called DynWVC1 and DynWVC2. Previous MWVC algorithms are evaluated on graphs with random or han
