Abstract: Examination timetabling is an optimisation problem, which regards the scheduling of a set of exams to a set of contiguous time slots, satisfying a set of constraints. The problem belongs to the class of NP-Complete problems and is usually tackled using heuristic methods. In this paper, we describe a solution algorithm and its implementation which makes use of the good features of a Greedy Randomised Adaptive Search Procedure (GRASP) and the Guided Local Search (GLS) meta-heuristic. The implementation of the algorithm has been experimented on the popular Carter|s benchmarks and compared with the best recent results.

Keywords: examination timetabling; GRASP; GLS; guided local search; metaheuristics; graph heuristics; optimisation; scheduling; greedy randomised adaptive search procedure; exam timetables.
