FET is open source free software for automatically scheduling the timetable of a school, high-school or university. It uses a fast and efficient timetabling algorithm. It is licensed under GNU/GPL.

The FET program is a straightforward tool designed primarily to run its timetable-generating algorithm based on its input data. As a scheduler of courses and activities, it supports a large variety of time and space constraints for teachers, students, and classrooms. Its plain and simple interface, consisting of drop down menus that open into new windows, is not very user-friendly and can be improved upon. The program is written in C++ and comes with well documented source code. This includes a document with an explanation of the program's powerful algorithm. Although the aesthetics of FET can be improved, it serves as a useful learning tool.

Good Features

• FET is free software (open source).
• Platform independent implementation, allowing running on GNU/Linux, Windows, Mac and any system that Qt supports
• Powerful flexible modular xml format for the input file, allowing editing with an xml editor or by hand (besides FET)
• Possibility to view the currently generated timetable without stopping the ongoing simulation (as html on hard disk)
• The resulted timetables are exported into xml and html formats
• Each constraint has a weight percentage, from 0.0% to 100.0% (some special constraints can have only 100% weight percentage possible)
• Possibility of adding multiple teachers and students sets for each activity. That is, each activity can have specified any number of students subgroups (sets) and any number of teachers (it is possible to have no teacher or no students set for an activity, also)
• Can generate multiple time-tables for the same constraints
• Can remove redundant constraints
• Time Constraints:

            - Constraint basic compulsory time
            - Constraint basic compulsory time
            - Constraint min n days between activities (to allow balancing the activities in a week)
            - Constraint activity preferred times
            - Constraint breaks
            - Constraint teacher(s) max (min) hours daily
            - Constraint teacher max days per week
            - Constraint teacher not available
            - Constraint teachers max gaps per week
            - Constraint activities not overlapping
            - Constraint min gaps between activities
            - Constraint 2 activities consecutive, grouped, and ordered
            - Constraint teachers max gaps per day

• Space constraints:

            - Constraint basic compulsory space
            - Constraint room not available
            - Constraint activity preferred room(s)
            - Constraint subject preferred room(s)
            - Constraints to control building changes for students and teachers (min gaps between building changes, max building changes per day, max building changes per week)

Bad/Unneeded Features

• Multiple language support
• Possibility to have no teacher
• Constraint on last class of the day
• Weights should be ranks instead of percentages

Missing/Needed Features

• A more user-friendly interface. The program shows nothing on startup. Everything must be accessed from drop down menus.
• Colorful time-tables
• FET is designed only for administrators. It lacks an interface designed for a single teacher to enter his or her own preferences and constraints
• Teacher preferences for courses
• Maximum distance between buildings
• Maximum time gaps between courses
