Hello Liviu!
I tried everything with example:
In official mode, I have seven school days from Monday to Saturday
In class 6A there is Math (4 = 1+1+1+1). I want them to appear on Mondays 2, 3, 5, 7 or 2, 4, 6, 7 meaning only 2 consecutive days of math will be allowed. What constraint do I have to use on the FET to solve it!
Do you mean Monday to Sunday?
Please add some carefully chosen min days between activities constraints.
hmmm.... I fear there is no easy solution.
maybe use variant a:
allow up to 3 consecutive days,
by adding a second min day constraint with wieght 100%, min day = 2, but only 3 subactivities.
maybe use variant b:
try to avoid consecutive days at all, (but in worst case still all might be consecutive),
by adding a second min day constraint with weight less then 100%, min day = 2, with all subactivities.
In my opinion, you put this RB into the FET but only for some teachers. Thank you very much!
It is best to keep implemented constraints in FET to a minimum, especially since this proposed constraint is so specialized.
A1, A2, A3, A4.
Doesn't it work if you add 100% min 2 days between A2, A3, and A4, and 100% min 3 days between A1 and A3 and A1 and A4? Or try other combinations if I am wrong?
Ok, thank you so much
