چکیده

Course timetabling problems are real world constraint optimization problems that are often coped with in educational institutions, such as universities or high schools. In this paper, we present a variety of new operators that can be also applied in evolutionary algorithms for other timetabling problems, such as, exam timetabling. Operators include violation directed mutations, crossovers, and a successful violation directed hierarchical hill climbing method. Tests are performed on a small portion of a real data and results are promising.

The Design of Memetic Algorithms for Scheduling and Timetabling Problems

There are several characteristics that make scheduling and timetabling problems particularly difficult to solve: they have huge search spaces, they are often highly constrained, they require sophisticated solution representation schemes, and they usually require very time-consuming fitness evaluation routines. There is a considerable number of memetic algorithms that have been proposed in the l...

A memetic algorithm for University Course Timetabling

We present here a metaheuristic approach to the university course timetabling problem using a memetic algorithm with a very effective local search. The algorithm was tested on the International Timetabling Competition benchmark instances. Results are encouraging and show that evolutionary computation with the help of local search can compete with succesful algorithms on the problem.

Using 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...

The Interleaved Constructive Memetic Algorithm and its application to timetabling

Timetabling problems are well known NP-hard constraint satisfaction, and real-world cases often have complicated and challenging structures. For such problems, we present a new hybrid method, “Interleaved Constructive Memetic Algorithm” (ICMA) that interleaves memetic algorithms with constructive methods. ICMA works using an active subset of all the events. Starting with a few events, in multip...

An Empirical Investigation on Memes, Self-generation and Nurse Rostering

In this paper, an empirical study on self-generating multimeme memetic algorithms is presented. A set of well known benchmark functions is used during the experiments. Moreover, a heuristic template is introduced for solving timetabling problems. The heuristics designed based on this template can utilize a set of constraint-based hill climbers in a cooperative manner. Two such adaptive heuristi...
