In this paper we report on a computational experience with a local search algorithm for High-school Timetabling Problems. The timetable has to satisfy "hard" requirements, that are mandatory, and should minimize the violation of "soft" constraints. In our approach, we combine Simulated Annealing with a Very Large-Scale Neighborhood search where the neighborhood is explored by solving an Integer Programming problem. We report on a computational experience validating the usefulness of the proposed approach.

Abstract
In this paper we report on a computational experience with a local search algorithm for High-school Timetabling Problems. The timetable has to satisfy "hard" requirements, that are mandatory, and should minimize the violation of "soft" constraints. In our approach, we combine Simulated Annealing with a Very Large-Scale Neighborhood search where the neighborhood is explored by solving an Integer Programming problem. We report on a computational experience validating the usefulness of the proposed approach.
