Constraint: Room: Minimum occupancy

Specification

Checks the number of students placed in the room.

Deviation

Broken if the room is not occupied up to its minimum occupancy. The behaviour when the room is empty depends on the constraint checking mode:

Strict mode

An empty slot produces a full penalty.

Relaxed mode

An empty slot is not penalized.

Comments

The resulting penalty is the base constraint penalty multiplied by the difference between actual and minimum occupancy.

This constraint is turned off by default.
