Title: Exceptions for time constraints
Post by: y on November 03, 2012, 04:12:04 PM
It would be nice to have the ability to add some exceptions to time constraints.

Eg, when setting max hours / day for all teachers = 5, to put an exception for teacher A and set it =4. As it is right now, I have to add the constraint max hour /day for each one teacher.

Furthermore, if I put min hours daily for all teacher = 3 and at the same time put teacher B to have a minimum hours per day = 2, then the first constraint prevails. If there was an exception to the first rule and put =3 for all teachers, except teacher b where it is =2.

I hope you get my point.

Thank again for the great software and all your effort!!!

For max hours daily, exceptions from your case work as it is now, because the stronger constraint wins. (You said all = 5 h, single = 4 h.)

For min hours daily, suggestion is already added in the TODO (indeed, you need to add a constraint for each teacher, in this case).

Yes, you 're right, my fault.

That's very nice then. I haven't noticed it.

Thanks again!
