One more thing - is there a way to display the rooms on the individual timetables? Now they are only assigned to 1 activity/student, but I need them to be on every timetable...

So without setting prefered rooms, I cannot schedule the rooms?

Thanks you very much, it does. Any advice on how to schedule the rooms?

I now did it differently - added activities for every teacher (and removed that activity from one person). It works now, however, it doesn't schedule the rooms at the moment

And is there an easy way to see how many people attend a subject at a certain time?

Thanks. I still have two questions:
- what did you mean by "You can add other activities with teachers and constrain them similarly with the students.", will it be possible to generate a timetable for the teachers this way, and how?
- isn't it true that a room can only hold 1 activity (so that it would be impossible to have the rooms scheduled as well), or does this not apply to semi-activities?

Edit: I now applied a space constraint for one activity and that made it impossible for FET because a room cannot have multiple activities

Hmm, thanks, seems to be working. However, is it true I can't get the rooms to be calculated in that case?

So there's no way to tell fet "I want those students to attend those subject but you go figure out in what groups"?

Hmm ok. But then, how should I input it in order for FET to split the groups automatically?

Good question - in the input file I only put 267 for 3 activities... so is my input file incorrect?

It's just numbers so not really a need to keep it private. the act.txt file is the one I used to import the activities.

The problem is the way I did it it every student should only have 3 hours tops, some 2, so I don't understand how FET get's the 5 to 7 hours...
if necessary I could provide my .FET file?

I'm not sure I understand you correctly. For instance, I now have activity 1 with 27 students, split in 2. When I try to generate a timetable I get this warning:
Cannot optimize for subgroup 1 Automatic Subgroup, because the number of hours for subgroup is 5 and you have only 1 days x 3 hours in a week.

For the small groups the number of hours is almost always 4.

The line I import as activity:
"Students Sets","Subject","Teachers","Activity Tags","Total Duration","Split Duration","Min Days","Weight","Consecutive"
1+2+3+4+5+8+16+22+37+72+96+108+110+113+123+131+145+165+168+173+206+245+248+254+259+264+267,1,1,,2,1+1,1,95,0
where 1 is both the lesson and the teacher

I had to work with other data so I exported it in a way I thought was best; first, I ordered by subject and checked which student attended that subject, and then made one line for that subject with as student set all the students attending. That ended up in large groups, so that didn't work.
Now I tried to make 3 activities per user, one for every subject he was attending, but that didn't work either because one teacher now has, for instance, 27 hours where there are only 3 available.

BTW I already added a year 'A' and for every person attending a student group with the number that student has.

Something else: with the first option I had it split into parts (so Split duration 1 and Total duration 3, when I thought 3 groups were necessary, for instance).

I tried to do that but then the groups with say 40 people don't get divided, correct? At least when I tried it that way it was stuck after the 6 biggest groups...

Hi all,

I'm currently trying FET because I need to make a timetable for an information evening with about 70 subjects. People have provided their choices (first, second and third) and I have three rounds; I preferably want everybody to get all their 2 (mandatory) or maybe 3 choices, if they provided a third one.
Some subjects have about 50 people that want to attend, others have just a few; but my question is, how can I tell FET to split the big groups in smaller chunks? I can't do it myself because who is in which group depends on what other subjects they want to attend.

Anybody know something? So basically I want to tell them which groups have which choices and then mix up the groups. Should I use subgroups for this or something?
