Mikko, the variant with "min" is very complicated. I think I will do only the "max" variant, hoping it is the most important and useful. I will let you know when ready. The most important and difficult part is done, the generating code, but now comes the tedious part of the interface.

What do you think about "min"? Is it not important?

Yes, the problem is always too crowded terms. If that is sorted out, there is no need for min, because activities are more even with just "max". A teacher with very small amount of activities, the first problem can be "min" but it can be handled with "max".
And, too many constraints will be a mess. It already is, for me.

But this max will make things much easier.

Ok, thanks. Simple question and answer is not. Agreed.

One simple question:
If a teacher has for example 75 activities on the wholwe year, what could be the proper min and max for one term?
Or when teacher has 62? Or 82?

75/5 = 15 (min 12, max 17?)
62/5 = 12,4 (min 10, max 14?)
82/5 = 16,4 (min 15, max 19?)

Min for tearhers in  maybe needed, when a taecher has only few activities.
I'm trying to have this done today, but I certainly will test ýour new constrains  immediately.  If it gives better results its possible for me to make new one on Saturday/Sunday

So, teacher(s) max/min hours per term, 4 types of constraints. The min will have a check box, "Allow empty terms".

Is this needed also for students?

How about the min (for teachers) - is it useful? What do you think? And with the check box allowing empty terms?

Will you be able to test? I might have tomorrow evening a working version, if I move fast. I can do my own tests, but I prefer to see the real life in action.

Not needed for students in our system. We only want that they have at least 3 lessons a day, nothing more is needed. Timetable is so full that it dosn't need more constrains.

Yes, I agree. I added this in the TODO and I will think of it for the future. If I find sponsors, I will do it rightaway. My price for this feature is 1,600 (one thousand six hundred) euros.

Sounds fair. I have to find some time to inform principals in Finland about FET. I find it super. It works the way I think and it makes things manageable.

Unfortunately it's not possible for me to support you financially. Things go so, that municipality decide what to buy and I can only tell my opinion. Maybe I can tell it louder.

Maybe I should add in the TODO the constraints of type teacher(s) min/max hours per term.

Certainly that would make life easier as a 5-term timetable maker for 50+ teachers

Now I realize why those colors are not always good. Green makes me think thats ok

Baaaad! Thanks.

Now I have a problem. There is something wrong and I cant find what. Many constraints, too many...

This is what I got now

Please check the constraints related to following possibly problematic activity (or teacher(s), or students set(s)):
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
Id: 1960 (    1/6 - kilann,kulout - B1RU - RU - 7A,7B)
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

Btw, is there anyway to make constraints as a batch, not making them one by one?

Sorry, you did not mean max 10, but 10 constarints
So busy not having time to read

Thanks!
I found that myself too (always asking, not thinking...)
kartar is ok indeed now, but in the previous 150 versions she tend to have uneven terms

So you think that 10 is not too tight to try? I'll do that.

My file is noway secret, but just now I will go on!

Hello!
I'm in a quite final state of making timetable. My main concern are uneven terms for certain teachers. I'm aware that this is because of other constraints - certain activities in certain terms or not in certain terms. Then there are other things too, like not many gaps per day or week.

Now the timetable takes 5-7 hours and I'd like have it ready today. So I need siome advise what I could try. For example "lyrpep", "kartar", some others too have difficulties with uneven workload.

So, whats wrong in mny file and what could I try?

This is a 5-term school, so 25 days, 5-terms, 4 hours a day.
Oh, it seems that my file is much too big...

Thanks for this!
I think this is quite doable for me, but not for my collegues (I have only two years left before retirement). I will check this when this timetable is ready.
