Instances for the University Course Timetabling Problem
Lately we have been working with algorithms for the University Course Timetabling
Problem (UCTP) that are specialised just for finding feasible timetables. The
problem is that existing instances are just too easy! We have therefore created
sixty new instances specially made to be "harder" with regards to
finding a feasible timetable. The instance files are in the same *.tim format
used for the International Timetabling
Competition. All instances have at least one feasible solution and were
generated by Rhyd Lewis using an automated instance generator by Ben Paechter.
