I'd like a group of students to have most of its activities in a given room (max 2). I tried to assign a preferred room for activities, setting a room as home room for this group, but timetables are not satisfactory. I mean this group is allocated to other rooms too. What should I do?
I sadly don't understand your problem. Home rooms should work correct. Did you set weight up to 100%?
Sure it was set to 100%. It began working after I had used subject+tag preferred room.
May it be the matter of constraint introducing order? Preferred room for a group worked for me too previously. As I remind I've set this constraint at the beginning of schedule building.
Ah. ok.
Home room constraints are only used by the activities if no other room constraints refer to that activity.
