nono, it's not checked. it's one of the misteries of this century. besides, i add the smileys from the list of smileys. i click on the icon. Smileys hate me :-)

hey, it works if i add the nose by hand,jolly good :-D

right, i tried the 5 dummy activities with all teachers full time in there, but i get no timetables. it gets stuck at 288. I think I will do it old times: generate and generate and generate until I get a timetable with no free days for full tiem teachers :-)

But why don't you allow a free day for a full-time teacher?

Can you please sent me your latest file (data set). i will keep privat, but i can mybe see solutions if i have that file. check my mail add www.timetabling.de

in my opinion i also prefer a free day to that teachers. if there is realy such a rule and your boss ask about that, you can still say that that teacher do surveillance at his free day.

oh, we don't have a boss. It's a public school so the boss would be the proimer minister, in a way :-)
Teachers must have classes everyday. All of us would be very pleased to work many hours during 4 days and have a free day, but it's against the law, only possible for teachers who work part time (half of the hours).
I'll send you the file, volker, so you can tell me what I'm doing wrong. thanks

Silvia, I could tell you how to make a non-adaptable constraint min hours daily for some teachers (to not allow empty days). It is not difficult to make. You might need to hire a programmer to implement my advice. Or maybe you know a bit C++ and how to compile FET from sources.

I could make an option for official FET: adaptable/non adaptable check boxes for min hours daily for teachers/students. But people don't understand this and they will probably make mistakes/obtain impossible timetables. That is why I made default teachers min hours daily adaptable and students non-adaptable.

OK, I'll ask at school if someone know c++ (not me) and can give me a hand. Thanks Volker, you're taking so much trouble to help me, I'm so sorry and so thankful :-)

well, I have decided not to try to get timetables without free days for teachers, it's too much work. i've just generated and generated, and finally I got a timetable with only 3 teachers with an illegal free day, so what I'll do is modify those timetables by hand.
When I finish this, I'll add the rooms by hand and voilà, the timetables will be ready :-D

I thank you guys very much because this wouldn't have been possible without your program and your help, thanks a bunch.

Oh, and I warn you

I won't stop suggesting improvements for FET, hehehhe. You know my personal fight about classrooms, don't you? hahhahaha
