FET is a free timetabling program for schools, high-schools and some universities. FET uses an efficient and fast timetabling algorithm and it is licensed under GNU/GPL.

NOTE: The Mac OS X (Intel) FET binary is contributed by Yushun Yuen. All problems regarding it should be reported on the dedicated FET forum thread.

Here are some key features of "FET":

· FET is free software, licensed under the GNU GPL v2 or later. You can freely use, copy, modify and redistribute it
· Localized to en_US (US English, default), ar (Arabic), ca (Catalan), da (Danish), de (German), el (Greek), es (Spanish), fa (Persian), fr (French), gl (Galician), he (Hebrew), hu (Hungarian), id (Indonesian), it (Italian), lt (Lithuanian), mk (Macedonian), ms (Malay), nl (Dutch), pl (Polish), pt_BR (Brazilian Portuguese), ro (Romanian), ru (Russian), si (Sinhala), sk (Slovak), sr (Serbian), tr (Turkish) and uk (Ukrainian) (incompletely for some languages)
· Fully automatic generation algorithm, allowing also semi-automatic or manual allocation
· 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 interface)
· Import/export from CSV format
· The resulted timetables are exported into HTML, XML and CSV formats
· Very flexible students (pupils) structure, organized into sets: years, groups and subgroups. FET allows overlapping years and groups and non-overlapping subgroups. You can even define individual students (as separate sets)
· Each constraint has a weight percentage, from 0.0% to 100.0% (but some special constraints are allowed to have only 100% weight percentage)

Limits for the algorithm (all these limits can be increased on demand, as a custom version, because this would require a bit more memory):
· Maximum total number of hours (periods) per day: 60
· Maximum number of working days per week: 35
· Maximum total number of teachers: 6000
· Maximum total number of sets of students: 30000
· Maximum total number of subjects: 6000
· Virtually unlimited number of activity tags
· Maximum number of activities: 30000
· Maximum number of rooms: 6000
· Maximum number of buildings: 6000
· Possibility of adding multiple teachers and students sets for each activity. (it is possible also to have no teachers or no students sets for an activity)
· Virtually unlimited number of time constraints
· Virtually unlimited number of space constraints


A large and flexible palette of time constraints:
· Break periods

For teacher(s):
· Not available periods
· Max/min days per week
· Max gaps per day/week
· Max hours daily/continuously
· Min hours daily
· Max hours daily/continuously with an activity tag
· Respect working in an hourly interval a max number of days per week

For students (sets):
· Not available periods
· Begins early (specify max allowed beginnings at second hour)
· Max gaps per day/week
· Max hours daily/continuously
· Min hours daily
· Max hours daily/continuously with an activity tag
· Respect working in an hourly interval a max number of days per week

For an activity or a set of activities/subactivities:
· A single preferred starting time
· A set of preferred starting times
· A set of preferred time slots
· Min/max days between them
· End(s) students day
· Same starting time/day/hour
· Occupy max time slots from selection (a complex and flexible constraint, useful in many situations)
· Max simultaneous in selected time slots
· Consecutive, ordered, grouped (for 2 or 3 (sub)activities)
· Not overlapping
· Min gaps between a set of (sub)activities


A large and flexible palette of space constraints:
· Room not available periods

For teacher(s):
· Home room(s)
· Max building changes per day/week
· Min gaps between building changes

For students (sets):
· Home room(s)
· Max building changes per day/week
· Min gaps between building changes

Preferred room(s):
· For a subject
· For an activity tag
· For a subject and an activity tag
· Individually for a (sub)activity

Requirements:

· Apple's developer tools installed.
· Qt 4.3.0 or later to compile.

What's New in This Release: [ read full changelog ]

· Each constraint can be activated/deactivated and also each constraint may have an optional comment. The user can sort the constraints based on their comment. These special functions can only be accessed from all time/space constraints dialogs (suggested by George Miliotis, Davide G. M. Salvetti and maybe other users).
· Each activity may have an optional comment (suggested by K, m and maybe other users).
· The command line version now saves the current timetable and the highest stage timetable if it receives SIGTERM from the user, then exits (suggested by Davide G. M. Salvetti and maybe other users).
· Added a Vietnamese translation, by Nguyen Truong Thang.
· Minor interface bug fixes.
· Updated the Saudi Arabia examination timetable file, by Silver.
