MIPLIB, short for Mixed-Integer Programming Library, is the standard test set used to compare mixed-integer solvers. It was first released in
1992 by Robert E. Bixby, E.A. Boyd, and R.R. Indovina. Naturally, as mixed-integer solvers become more accessible, more industries integrated mixed-integer solvers, and the size of instances increased, new iterations of MIPLIB were required. Releases followed in 1996, 2003, 2010, and 2017, with these releases following an unofficial seven year schedule. The customary seven years has now passed since the last release, and a new iteration of MIPLIB, MIPLIB 2024, is being put together.
In its current state, MIPLIB 2017 serves as the standard benchmark set for comparing the performance of different mixed-integer solvers. It was compiled by a group of 21 interested researchers, including representatives of the development teams of nine mixed-integer solvers, with submissions derived from 66 unique submitters (including bulk submissions from online optimization servers and optimization competitions). Nevertheless, the mixed-integer landscape has changed in seven years. New applications of mixed-integer solvers have arisen, and an increasing amount of industries are now using mixed-integer solvers.
Therefore, we are advertising the submission for MIPLIB 2024:
https://miplibsubmissions.zib.de/
To emphasize the importance of MIPLIB: It is the standard benchmark library for mixed-integer solvers. Having one of your instances included in this benchmark guarantees that mixed-integer solvers as a whole try and improve solution time on the included instance. If the instance is representative, then performance will at least partly generalize to other similar instances that you might have. It also guarantees that academics will regularly consider new solving techniques for your instance. Having as many industries and applications represented as possible is critical for MIPLIB 2024 to be an appropriate benchmark for mixed-integer solvers. Please submit any and all instances you are comfortable sharing to: https://miplibsubmissions.zib.de/
Extended Deadline: 31.12.2024
Instance specifications: Anything that is classified as a mixed-integer linear program (this includes binary and integer programs). Instances containing indicator and SOS constraints are also welcome.
