Abstract

The EXAMINATION TIMETABLING problem regards the scheduling for the exams of a set of universitycourses, avoiding the overlapping of exams having students in common, fairlyspreading the exams for the students, and satisfying room capacity constraints. We present a familyof solution algorithms for a set of variants of the EXAMINATION TIMETABLING problem. The algorithms are based on tabu search, and theyimp ort several features from the research on the GRAPH COLOURING problem. Our algorithms are tested on both public benchmarks and random instances, and theyare compared with previous results in the literature. The comparison shows that the presented algorithms performs as well as constructive methods and memetic algorithms, and onlya decomposition based approach outperforms them in most cases.
