[Opt-net] MIPLIB2010 – Call for contribution

[Timo Berthold]

Dear colleagues.

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
