Dear SCIP community,<br>
<br>
my apologies for any accidental cross-posting. Please find below the
official release announcement of the new Mixed Integer Programming
Library, MIPLIB 2017, for which we have received many contributions
by colleagues on this mailing list.<br>
<br>
Thank you and happy benchmarking,<br>
Gregor<br>

Dear colleagues and friends of MIP,<br>
<br>
We are happy to announce the official release of the new MIPLIB
2017, the 6th edition of the Mixed-Integer Programming LIBrary, at<br>
<br>
<a class="moz-txt-link-freetext" href="http://miplib.zib.de/">http://miplib.zib.de/</a><br>
<br>
Since 1992, MIPLIB has served as an important stimulus for
researchers and practitioners. The new library has been selected
from more than 100 new submissions and publically available
instances. The final collection consists of over 1000 MIP models
and is by far the largest MIPLIB that was ever created.<br>
<br>
For the first time, instances have been selected using a fully
data-driven process to represent the diversity of MIP best
possible. A subset of 240 benchmark instances has been carefully
selected such that the shifted geometric mean over all these
instances allows, as much as possible, a balanced but challenging
assessment of current MIP solver performance.<br>
<br>
The web site provides an overview of the selection methodology and
convenient access to instance sets, individual instance
information, supplementary material, best known solutions, and
much more. A more detailed report is currently in preparation.<br>
<br>
Finally, we would like to encourage the community to become active
and contribute bibliographic information and improving solutions
to more than 300 currently unsolved problem instances. Also
general feedback and suggestions for improvements are always
welcome.<br>
<br>
At this occasion, the committee of MIPLIB 2017 would like to thank
all<br>
involved people for their contributions and instance submissions
to the<br>
new edition of MIPLIB!<br>
<br>
Happy problem solving,<br>
<br>
Ambros Gleixner, Gregor Hendel, and Gerald Gamrath<br>
on behalf of the MIPLIB committee<br>
