In the attached file you will notice that there are breaks in the subject, the idea is that they are one after the other, there should be no gaps between breaks, examples: in the image see 1st year, on Monday they start class at 7:45 am with Orientation and they finish at 9:15 am, after that comes a one-hour break from 9:15 to 10:00, then comes the general recess, what we want is for there not to be those breaks between subjects... Thanks everyone, I use Google Translate.
Hello!
In FET, if you don't specify a constraint, it is not applied. You need to add constraints students (set) max 0 gaps per week and maybe also constraints students (set) begin early max 0 beginnings at second hour.
