I have a quesion about choosing rooms.
Science can be in lab 1 or lab 2. The space constraint for rooms option "a subject has a preferred set of rooms", does this mean it can choose from this set of rooms? That is what I am hoping.
Thanks for your time and all the previous help, things are going very well! :)
yes. roomS constraints select only a single free room from the set you selected. so it is correct to use roomS constraint if it doesn't matter if it is in lab1 or lab2. fet will choose one free lab-room.
