Adaptive search techniques for problems in vehicle routing, part II: A numerical comparison [PDF]
Research in the field of vehicle routing often focused on finding new ideas and concepts in the development of fast and efficient algorithms for an improved solution process. Early studies introduce static tailor-made strategies, but trends show

Formulation space search approach for the teacher/class timetabling problem [PDF]
We consider the well known NP-hard teacher/class timetabling problem. Variable neighborhood search and tabu search heuristics are developed based on idea of the Formulation Space Search approach.

Heuristics for NP-hard optimization problems - simpler is better!?
We provide several examples showing that local search, the most basic metaheuristics, may be a very competitive choice for solving computationally hard optimization problems. In addition, generation of starting solutions by greedy heuristics should be at

Which Local Search Operator Works Best for the Open-Loop TSP?
The traveling salesman problem (TSP) has been widely studied for the classical closed-loop variant. However, very little attention has been paid to the open-loop variant.

In this paper a learning based local search approach for propositional satisfiability is presented. It is based on an original adaptation of the conflict driven clause learning (CDCL) scheme to local search. First an extended implica- tion graph for complete assignments of the set of variables is proposed.

AbstractImprovement methods constitute the backbone of most metaheuristics. These methods repeatedly perform slight, local modifications on a current solution to the problem. Hence, for any solution, a set of neighbor solutions must be defined. Clearly, the definition of this set depends on the problem modeling. However, a natural neighborhood may turn
