Since its first release in 1992, the MIPLIB has become a standard test set
used to compare the performance of mixed integer linear optimization software
and to evaluate the computational performance of newly developed algorithms
and solution techniques.
Seven years have passed since the last update in 2003. Again, the progress in
state-of-the-art optimizers, and improvements in computing machinery have made
several instances too easy to be of further interest. New challenges need to
be considered!
Last year a group of interested parties including participants from ASU, COIN,
FICO, Gurobi, IBM, and MOSEK met at ZIB to discuss the guidelines for the 2010
release of the MIPLIB. It will be the fifth edition of the Mixed-Integer
Programming LIBrary.
Therefore, we are looking for interesting and challenging (mixed-)integer
linear problems from all fields of Operations Research and Combinatorial
Optimization, ideally ones which have been built to model real life problems.
We would be very happy if you contributed to this library by sending us hard
and/or real life instances.
We have recently opened our submission web page and are looking forward to
your contributions:

Thanks and best regards,
Timo Berthold in behalf of the IP group at ZIB.
