One more question regarding Teacher interval max days per week: I would like teacher X to work:
-1)4 days/week
-2)starting each of these days at 13.00 (13.00=the 4th interval, the first interval begins at 7.30, the 2nd at 9.30 and the 3rd at 11.20)

So
1) -> Teacher max days per week -> select teacher, 4, 100
2) -> Teacher interval max days per week -> select teacher, interval start hour=13.00, End of day,  4 or 5 - it does not matter, 100

It does not work as expected...

What constraints should I add/modify?

You are wrong I think.

First of all, if you want teacher T to work from 13 to end of day each day, you better use teacher not available constraint times constraint (faster, more efficient than interval max days per week).

Then, if you still want to use constraint interval max days per week, if teacher T works from 13 to end of day, then add a constraint interv. max days per week, from first hour to 13, max days = 0.

Please let me know.

I've used Teacher not available and it works great.

So the constraint "Teacher interval max days per week" what is used for? Could you give me an example where max days != 0 ?

Thank you,

Horatiu needed that teacher or students worked maximum 2 days per week in the very late hours (20-22).

Or maybe others need teachers or students to work maximum 1-2 times per week in the last hour.
