Min gaps per day for all teachers

[Majid]

Hi!
I need a constraint like "Min gaps per day for all teachers" to define no gaps for any teacher daily
Thanks for your help!

I do not understand, min gaps or max gaps?

You have available constraints teachers max gaps per day = 0 or teachers max gaps per week = 0 if you want no gaps for any teacher. I think it is better to use max gaps per week = 0, I think it is faster (I didn't try).
