Please, can you help me with this?
I have updated the old timetable with new classes and new teachers using the same parameters, but it no longer works.
Maybe it's something really easy, but I'm absolute newbie on FET.
Any hints?
Thank you
Paolo
The problem seems to be the constraint "max hours daily" for teachers. If you set max hours = 6 (instead of 5), the timetable solves really fast. If you use two constraints, i.e. one constraint with max hours = 5 and weight 99.99% and another constraint with max hours = 6 and weight 100%, the timetable is solvable again. It just needs a little more time.

Dear Vangelis
thank you so much for the quick reply.
The problem is that legally we cannot stay in the classroom for more than 5 hours/day.
We will try to figure it out.
It's very likely that I will bother you again.
Have a good weekend

The problem seems to be the teacher Romeo. His activities have duration = 2. Is it possible to change it? Otherwise, I think he should have max hours 6 at least for one day... (edited) since he has 22 hours per week.

Vangelis, I don't understand your argument. There are 5 days, and max 5 hours per day means that the teacher can have even 25 per week.
Silly me, Vangelis told me that this teacher cannot have 5 hours per day, because he has only duration 2 activities :)
I'll add Vangelis' suggestion to make a test for this in the TODO.
