we are happy to announce the release of the SCIP Optimization
Suite 5.0. It consists of SCIP 5.0, SoPlex 3.1, ZIMPL 3.3.4, GCG
2.1.3, and UG 0.8.5. A corresponding new version SCIP-SDP 3.1.0
has been released at http://www.opt.tu-darmstadt.de/scipsdp/.
The SCIP Optimization Suite 5.0 provides
- detection and handling of symmetries in MIP
- major improvements in cutting plane separation
- a new adaptive large neighborhood search heuristic
- improved handling of bilinear and quadratic terms
- conflict analysis through dual solutions of bound exceeding LPs
and many more features. All in all, SCIP 5.0 is 41% and 17%
faster than SCIP 4.0 on our extended MIP and MINLP test sets,
respectively. On hard MIPs a speed-up factor of 2.1 was
achieved.
For more information check out our website http://scip.zib.de and

improvements to the SCIP Optimization Suite, which is available
