The generation of timetables with good quality is a critical factor in any educational institution. This is considered a complex problem because it involves several types of information, such as schedules, course subjects, teachers and students. Several search strategies have been applied to solve timetabling problems, whose constraints may vary from one educational institution to another. Most educational institutions still prepare their timetables manually, which is a highly time-consuming process and subjected to errors. Several approaches to solve this problem are also found in technical studies, which use stochastic search methods due to the problem’s complexity. The search optimization methods used in this work to solve the timetabling problem are genetic algorithms and the clonal selection algorithm, whose satisfactory results when applied to optimization problems are reported in the literature. Two decision support systems were developed in this work, combining heuristic techniques with the genetic algorithms and the clonal selection algorithm. The purpose of this research is to make a comparative analysis of these two techniques in order to determine which one offers the most promising results for solving the timetabling problem.
