We built a real-life instance modeling the second semester of the last year of Bachelor in Computer Sciences at Université d’Angers.

The instance contains 5 mandatory courses and 2 courses to choose among 4 additional courses. The instance thus consists of 9 courses decomposed into 24 parts, 45 classes and 241 sessions. Courses are taught during 12 weeks, 5 days a week (Monday to Friday), where each day is divided into 1440 slots. At the Faculty of Sciences of Université d’Angers, course sessions last 1h and 20 minutes or 2 hours and start at regular intervals every 90 minutes starting at 8h00 and finishing at 19h50. The 90 minutes interval includes a 10 minutes break allowing students and lecturers to change rooms.

The instance contains 8 rooms, 12 lecturers and 67 students. In our case, student sectioning was performed in advance and prepartitioned the students into 4 groups. Lecturers are either course owners involved in all the parts of a course (lecture, tutorial and lab) or tutors that are involved in labs of different courses. There are 47 rules defined in the instance.

This instance can be downloaded in XML, JSON or DZN (with the specific tt_rules_constraints.mzn file).
