You are welcome!  :)

I thought you would be a bit disappointed that a solution is only possible with 4 exceptions.

I believe there is an error somewhere.
the nsrt version fails to resolve the file attached below (does not exceed 16 placed activities)!
I also attach the same file resolved by the official version with the gaps..

may be a limit to satisfy the repetition condition implemented in the nsrt version. and we must break this condition or give it a weight less than 100% specially for such file attached above

In this file we have two sets of teachers; The first set has 12 activities, and the second set has 13 activities.
While the number of real rooms is only 10 .
So we clearly see that the number of Rooms is smaller than the number of activities for each element of the two sets.
Thus the solution with this version is impossible.
Repetition must be allowed.
I suggest adding a checkbox to allow or disallow repetition... or add weight to this constraint.

I am sorry, but adding weight/exceptions is not possible.

No problem Dear Liviu 🙂
... So the method for gaps as described above remains valid in such files ... like workaround.

It seems to work: https://lalescu.ro/liviu/fet/download/custom/nsrt/

I hope you can allow a room 3 times if you allow 2 exceptions (as opposed to two rooms two times each). But if not, I could find a solution also for this.

I am so tired  :)

Please read the readme.txt near the end and see your example (which I modified), see the comments of the rooms.
