QuoteReally difficult? Probably I have no knowledge enough, and I haven't read the fet source code, but imagine something like that:Now there are some activities that remain without a classroom assigned, if there's no constraint related (maybe I'm missing something?). The idea would be, once the timetable is generated, to go through all the activities without room and assign it the first room available at this time slot. If there's a priority number for the rooms, the order to choose "the first room" would be this number, so this would mean the available room with the largest number.Actually, it's more or less what I would do if I had to do it manually.
QuoteYes, maybe for some situations, or for some teachers. But in my school there are always, at every time slot, one or two teachers of "surveillance". Their tasks are to look after students who are made out of class by behaviour reasons, or that feel ill, to go to the classroom if a teacher has not come, etc. These surveillances count equal than a break surveillance in order to make the timetable. So my strategy was the following: I defined two groups G1 and G2 (we call these surveillances "guardia") and as many activities as hours dedicated to these surveillances for every teacher (not everybody has the same number, depending on several factors). So FET distributes this hours in a random way, maybe at break time, or maybe at normal hours. So I don't decide previously who makes surveillance at break time, and if a teacher complains about it, I can say it's a software fault ;-)But if a teacher does not have break time surveillance I don't want this slot to be counted as a gap.

QuoteYou could add an activity tag for each activity and constraint preferred rooms, all rooms, for this tag.
QuoteIt might be easy to make that in a custom version. Because each slots can be or not considered a gap in teacher's timetable. And the good thing is that you are using GNU/Linux and I don't need to compile for you a Windows version. Let me know if you agree on a custom version and I'll send the code. Tell me the days and the hours when gaps should not be counted for teachers, 0 indexed. For instance, Monday first hour is day 0, hour 0. I do not promise a fast implementation, but I might do it soon.
QuoteWe do it this way:add a subject "surveillance".add activities to teacher that should to surveillance. (Activities with teacher name, no student, subject surveillance and duration 1. (...)
