comp08-2idx: Instance-to-Instance Comparison Results
Type: | Instance |
Submitter: | Matias Sørensen |
Description: | Instances comp01-21 of curriculum based course timetabling from the International Timetabling Competition 2007. These are time-assignment models (Stage I of the decomposed model), which are smaller than the full model, but still hard to solve. |
