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 now open submissions for MIPLIB 2024:

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/
Deadline: 30.11.2024
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.
