Perchè non si chiude?

[Sonibus]

Chiedo consigli!
Ho provato a generare 'orario ma su 628 attività ne ha collocate 627 e dopo un'ora ancora non si chiude cosa posso fare?
allego il file
Grazie mille

i checked your file.

There are 2 things you can do:

a) an easy solution, but the result is maybe not so nice
or
b) you need to hunt a bit a bug. that is a bit work, but after that you will get faster and nicer results.

you need to do this:
a) just let it generate some more time. i can't tell you how long it will need. maybe a few hours.

b) modify all min day constraints from 95% up to 100%
you will see the are a few activities with 9 subactivities. it is impossible to solve that with 100%. So:
b1) reduce that one down to 0%
or
b2) instead of 1+1+1+1+1+1+1+1+1 and 0%, maybe better an activity with 2+2+2+2+1 and 100%
you will see that there it stuck know pretty fast. you need to fix that bug.
as soon as you understood that bug, you need to fix that also. (i guess at least one more teacher or student need a double hour, but i didn't check it yet)
