If it's worth saying, but not worth its own post (even in Discussion), then it goes here.

Notes for future OT posters:

1. Please add the 'open_thread' tag.

2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)

3. Open Threads should be posted in Discussion, and not Main.

4. Open Threads should start on Monday, and end on Sunday.

The best way to win principals is to show them that a ridiculously complex constrain may be applied and calculated automatically.

4.5 school hours of S per week (4 hours on odd weeks and 5 hours on even weeks)
when there is the fifth hour in the week, then this hour may be the second hour of the subject S on that day
if it is on the same day, it should be immediately after the previous hour of the subject S
in the above case, it must be the last hour for the teacher
three classes of students are divided into 5 groups for the subject S
there are 4 teachers for those 5 groups, one teacher teaches groups number 2 and 4
there is a given list of students for groups 1, 3 and 5 and a combined list for students for groups 2 and 4
computer should divide the combined list into two separated lists (2 and 4) but they must not differ for more than 4 students in size
as one of those groups (2 or 4) are always idle, the subject M which is equally divided, must be taught then - or the S should be the first hour of the day
for there are only 4 hours of subject M per week
there are only 3 teachers of M
there are also 3 hours of subject A per week for those same students in 5 differently set groups
there are 5 teachers of A, but one of them also teaches the group number 1 of S
it would be nice but not mandatory if the number of waiting hours for students were 0

This is a real life example, I have discussed 1 hour ago with one of the teachers (math teacher) in one of our schools. It is not the most complex demand we had, by far.

S = Slovenian language M = Math A = Anglescina (guess what that is)

fair enough, I was underwhelmed by your initial post describing it but I agree that showing that your system can handle weird constraints in real examples is an excellent demonstration.

The record thing to me just happens to be a good demonstration that you're not just another little startup with some crappy schedualling software, you're actually at the top of the field in some areas.
