Hello,
I have an issue and I can't find a way around it by myself, but maybe I'm missing something.
I have 5 lunch activities with preferred time slots for each student. One for each day of the week.
My issue is that I would like to use the ConstraintStudentsSetMinHoursDaily and that I don't have a way to ignore my lunch activities with this constraint. Meaning that if fet finds a timetable with a day off (which is allowed) the ConstraintStudentsSetMinHoursDaily will make it impossible because there will be the lunch activity no matter what. Indeed, if we have a day with only the 30min lunch activity for the student and the minHoursdaily constraint is set to 1 hours it won't be good..
One way to solve it would be to have a ConstraintStudentsSetMinHoursDaily with an activity_tag and i'd add an activity_tag to all my activities except the lunch ones.
If you understand my issue and know how I can accomplish that that would be amazing.
Thanks!

It is already in the TODO, see items 66, 145, and 248. I added you in the item 248.
Thank you for the suggestion! Unfortunately, the trick to use constraints activities occupy max time slots from selection I think does not work in your case, since you need to allow empty days.
This is a difficult constraint. I am willing to try and make it if I will get substantial financial support for this.
Oh I see, thank you for the fast answer. Hopefully you'll get financial support, fet is amazing and I really appreciate the support!
