| Description: | This CNF generator returns a CNF that describes the course registrar problem; that is, where should each class be taught based on classroom sizes and times of day. The default values are for a small school, i.e. 5 classrooms and 40 classes, spread across 8 class times during the week. Larger problems demand much larger times to process. |
