Our school have Lunch lesson at the 7th period. Teachers teach the 7th period can back to school at the 10th period. So I cannot arrange lesson for them at the 9th period.
6th period
7th period <--Teachers have lesson here,
8th period --X-- Lunch break (added by break time)
9th period <-- cannot have lesson here.
10th period
I used the time constraints for all teachers: max hours daily in interval
Interval start hour=7
Interval start hour=9
Max hours daily=1
But it doesn't works... Did I misuse the function?
Please make the interval [7, 10). It is like in mathematics, includes 7 but not 10.
thank you :)
