New description:
"SCIP is currently one of the fastest non-commercial mixed integer
programming (MIP) solvers. It is also a framework for Constraint Integer
Programming and branch-cut-and-price. It allows total control of the
solution process and the access of detailed information down to the guts
of the solver." -- http://scip.zib.de/
Features interesting to Sage:
* SCIP is pretty fast for Mixed Integer Programming
* SCIP is a Constraint Integer Programming solver and allows non-linear
constraints
* SCIP's source code is available
However, we don't have the right to redistribute the SCIP source code.
Thus, the attached SPKG is empty except for the spkg-install script etc.
To build a SCIP for Sage do:
* download the ZIB Optmisation Suite from
http://zibopt.zib.de/download.php?fname=ziboptsuite-2.0.1.tgz
* place the files `scip-2.0.1.tgz` and `soplex-1.5.0.tgz` in the `src/`
subdirectory of the attached SPKG
* install the SPKG
* apply the attached patch and `sage -b`
