In this contribution. a user-friendly timetabling tool is introduced that can create feasible and efficient school timetables in a few minutes. The tool is based in an adaptive algorithm which uses evolutionary computation techniques (Beligiannis et al. 2006). The algorithm has been tested exhaustible with real data input derived from many Greek high-schools, producing exceptionally results. Moreover. the user friendly interface of the presented tool has been taken into serious consideration in order to be easy for anyone to use it. Nevertheless, the main advantage of the presented tool lies in its adaptive behaviour. The users can guide the presented timetabling tool, producing timetables that best fit into their needs.
