Minimum or Zero movement of Students (Classes)

[bharatstank]

Hello,

How to restrict "Zero or Minimum" movement of the Students (Classes) from one room to another room for the back to back classes.

Home room can not define because:-
1. Number of rooms are less
2. Number of Students (Classes) are greater than the number of available rooms

Thank you for your support in advance

Thanks
Bharat

i suggest to use home rooms constraint, even there are less rooms.
that mean of course a few groups must share a room. count the number of hours and check if they can share a room. in best case groups can share.
if you have bad luck, than they can't share a single room. in that case you sadly need to place them into 3 (or more) rooms. maybe to it with the group with the lowest number of home rooms numbers, maybe do it with the group with the lowest number of students, maybe do it with the oldest students, maybe .... there are many variants.
