Dear list,

rather by random, I encountered a freeware featuring most features named 
here. It might be worthwhile asking its author (Timo Leuders) for 
sources (depending on libraries used). This freeware runs in wine, 
anyway, and implements an algorithm called "simulated annealing".

All URLs I found about it were German:
1. http://wiki.zum.de/SitzplanManager
2. http://www.forum-schule.de/\
3. http://www.cornelsen.de/kts/1.c.316517.de

This English text is about the underlying algorithm:

It is also used for table-planning (schedules).
