A set of activities occupies min different rooms

[Prof info]

Hello Mr Liviu,

On the contrary with the constraint "A set of activities occupies max different rooms".

Is it possible to add a constraint
"A set of activities occupies min different rooms"
That allows the activities of a teacher occupies at least in 2 or 3... different rooms from a list of rooms

And if the number of teacher's activities equals the minimum number given as a parameter, each activity will have a different room from the other.

Thanks you  in advance

Hello, Prof info,

Thank you for the suggestion! I wrote it down in the TODO.

Unfortunately, it looks very complicated to implement and might be highly inefficient in the algorithm.

But is this constraint really useful for an institution?
