Instance Sets

For convenience, we provide the entire collection and the benchmark set ready as downloads. The other interesting subsets are provided as test files. A test file contains the instance names that are part of this set, one per line. In order to obtain such a set, please download the entire collection and restrict your attention to the instances listed.

Please note that some of those test sets may even change over time after new results become available, such that instances are no longer open or even hard. We also provide test files for the entire collection and for the benchmark sets, which simplifies certain operations on those files.

Test Scripts and Solution Information

Find below the latest version bash scripts for running different solvers and obtain a preliminary performance table. A solution checker is included to validate the feasibility of the reported solution.

We provide optimal and/or best known objective values and the feasibility status of all instances in the collection as a .solu file that can be used by the MIPLIB scripts and by IPET for validation. We try to continuously update this solution information in the future and provide versioned files to make this process transparent.
