Local search and constraint programming for the post enrolment-based course timetabling problem
We present a study of the university post-enrolment timetabling problem, proposed as Track 2 of the 2007 International Timetabling Competition. We approach the problem using several techniques, particularly local search, constraint programming techniques and hybrids of these in the form of a large neighbourhood search scheme. Our local search approach won the competition. Our best constraint pr...
متن کاملUsing improved Memetic Algorithm and local search to solve University Course Timetabling Problem (UCTP)
Course Timetabling is a complex problem, happening at the beginning of every semester at universities. In this problem, one of the most important issues is variety of constraints, which results in different ways of timetabling in different universities. Comparing to exact methods which take lots of time to solve UCTP, metaheuristic methods produce a feasible solution within reasonable computati...
متن کاملAn IP-based heuristic for the post enrolment course timetabling problem of the ITC2007
Track 2 of the international timetabling competition 2007 was a post enrolment course timetabling problem. A set of events has to be assigned to a timeslot and to a room such that all students are able to attend their requested events while not violating the hard constraints. There are also soft constraints that make the timetable “nicer”. We present a deterministic heuristic that assigns event...
متن کاملA Modular Multiphase Heuristic Solver for Post Enrolment Course Timetabling
We give a short description of the solver that ranked third in Track Two of the International Timetabling Competition 2007 (ITC2007). It implements a heuristic approach based on stochastic local search and consists of several modules that were found to be useful in different phases of the solution process. Common to all modules is the consideration of only a subset of the constraints that have ...
متن کاملOn the performance of Scatter Search for post-enrolment course timetabling problems
This study presents an investigation of enhancing the capability of the Scatter Search (SS) metaheuristic in guiding the search effectively toward elite solutions. Generally, SS generates a population of random initial solutions and systematically selects a set of diverse and elite solutions as a reference set for guiding the search. The work focuses on three strategies that may have an impact ...
