Abstract
The minimum vertex cover (MVC) problem is a well-studied NP-Complete problem and has various applications. In this paper, a new heuristic approach has been proposed to find the minimum vertex cover of a graph. The proposed algorithm has been tested on random graphs and BHOSLIB instances. The results have shown that the proposed algorithm can yield better solutions especially on dense graphs for solving the minimum vertex cover problem.

On the Optimal Lawful Intercept Access Points Placement Problem in Hybrid Software-Defined Networks

TL;DR: In this paper, the authors proposed an improved equal-cost multi-path shortest path algorithm and accordingly proposed three SDN interception models: T interception model, ECMP-T interception model and Fermat-point interception model.
