Hello, there. First of all, thank you for this amazing job you are doing. I've got a question and I would really appreciate some help. We have 4 different groups.

Groups 1 and 3 follow this framework

1 period 8.15 - 9.15
2 period 9.15 - 10.15
Break
3 period 10.45 - 11.45
4 period 11.45- 12.45
5 period 12.45 - 13.45
6 period 13.45 - 14. 45

60 minutes each period

Groups 2 and 4 follow this:
1 period 8.15 - 9.15 (same as groups 1 and 3)
2 period 9.15 - 10.15 (same as groups 1 and 3)
3 period 10.15 - 11.15
Break
11.45 -12-45
12.45 - 13-45  (same as groups 1 and 3)
13.45 - 14.45   (same as groups 1 and 3)

Again, 60 minutes each period

Any suggestion?

I assume there is a teacher exhaustion (presence in two places at the same time) problem?

Add 7 slots per day. Add students not available for 1 and 3 in 3rd, and 2 and 4 in 4th.

And now a lot of work: for each teacher add n_days_per_week constraints activities occupy max time slots from selection. All activities of a teacher, select 3rd and 4th of a day, max occupied = 2.

You need to permit one more gap for each teacher each day.

Please let me know.

It is a matter of break in interval for teachers, which I am thinking of right now, but it is very difficult to implement for the general case.

Thank you for your answer. Could I possibly send you the file so that you can show me the example with one teacher? We are only 27. Not many
