A NNIA Scheme for Timetabling Problems

الملخص EN

This paper presents a memetic multiobjective optimization algorithm based on NNIA for examination timetabling problems.

In this paper, the examination timetabling problem is considered as a two-objective optimization problem while it is modeled as a single-objective optimization problem generally.

Within the NNIA framework, the special crossover operator is utilized to search in the solution space; two local search techniques are employed to optimize these two objectives and a diversity-keeping strategy which consists of an elitism group operator and an extension optimization operator to ensure a sufficient number of solutions in the pareto front.

The proposed algorithm was tested on the most widely used uncapacitated Carter benchmarks.

Experimental results prove that the proposed algorithm is a competitive algorithm.
