Course timetabling (ITC 2007 Track 3 - Curriculum Course Scheduling)
Problem description
Schedule each lecture into a timeslot and into a room.
Hard constraints:
-
Teacher conflict: A teacher must not have two lectures in the same period.
-
Curriculum conflict: A curriculum must not have two lectures in the same period.
-
Room occupancy: two lectures must not be in the same room in the same period.
-
Unavailable period (specified per dataset): A specific lecture must not be assigned to a specific period.
Soft constraints:
-
Room capacity: A room’s capacity should not be less than the number of students in its lecture.
-
Minimum working days: Lectures of the same course should be spread out into a minimum number of days.
-
Curriculum compactness: Lectures belonging to the same curriculum should be adjacent to each other (so in consecutive periods).
-
Room stability: Lectures of the same course should be assigned to the same room.
The problem is defined by the International Timetabling Competition 2007 track 3.
