ABSTRACT
Minimum vertex cover problem on a general graph is a NP-hard problem. The neighborhood relationship of a vertex plays a special role in Min-VC solving process. A concept of Max-I share degree is proposed in this paper, and a heuristic algorithm based on Max-I share degree is designed. Theory and experiment show that our algorithm can get almost the same result with the exact algorithm, Significantly better than other main heuristic methods in current.

We consider a particular bin packing problem in which some pairs of items may be in conflict and cannot be assigned to the same bin. The problem, denoted as the bin packing problem with conflicts, is of practical and theoretical interest because of its many real-world applications and because it...

One-reason heuristics are decision methods relying on only one good piece of information or one cue. In the past empirical studies of these heuristics, many participants used non-one-reason heuristics in spite of experimental conditions that called for the use of one-reason heuristics. In this...

Quality of test cases is determined by their ability to uncover as many errors as possible in the software code. In our approach, we applied Hybrid Genetic Algorithm (HGA) for improving the quality of test cases. This improvement can be achieved by analyzing both mutation score and path coverage...

In this work we investigate the algorithmic complexity of computing a minimum Ck-transversal, i.e., a subset of vertices that intersects all the chordless cycles with k vertices of the input graph, for a fixed k = 3. For graphs of maximum degree at most three, we prove that this problem is...
