SCIP MI(L)P and MINLP solver (and SoPlex LP solver) now Free Software
Hi,
I have good news for everyone interested in optimization software: SCIP
(https://www.scipopt.org/) has changed its license from the previously used
semi-free academic non-commercial license to the Apache 2.0 License, i.e., a
Free Software license and an OSI Approved Open Source license.
The license change also applies not only to SCIP itself, a solver for mixed-
integer linear (MIP/MILP) and non-linear (MINLP) problems, but also to the
underlying default continuous LP solver SoPlex.
The change has already been made in git. New tarballs will be released with
the next bugfix release (8.0.3), though I do not know when exactly that will
be.
So it should now be possible to package this in Fedora. In my experience,
SCIP performs much better than COIN-OR Cbc on MIPs (MILPs).
