News - Fair Isaac Announces Release of Xpress-MP 2008A
Fair Isaac today announced the release of Xpress-MP 2008A. Xpress-MP 2008A gives users more power to solve their hardest optimization problems even faster than before.
New optimization solvers in Xpress-MP 2008A include:
- Quadratically Constrained Quadratic Programming solver which can be used to solve portfolio optimization problems, optimization problems in statistics, and transport or facility location problems involving quadratic distance measures
- Convex Nonlinear Programming solver which can be used to solve certain nonlinear problems in engineering and chemistry
New features in Xpress-MP 2008A include:
- Multiple Solution and N-best Solution Support to give Xpress-MP users more information to make the optimal decision for their business problems.
- Deterministic Parallel MIP which for a given problem guarantees the same optimal solution every time it is run.
- Xpress-Tuner to give users the power to tune the Xpress-Optimizer to their specific problem. No knowledge of control parameters is needed so even novice users of Xpress-MP can now fine-tune the Xpress-Optimizer to unleash Xpress-MP’s full power for their problems. This full release of the Tuner improves on the beta version with Parallel solving, improved tuning methods and streamlined disk usage.
Xpress-Optimizer 19.00.00
Optimization performance has been improved across a wide range of models. The table below shows the performance comparison with release 2007B for the Dash standard QA set of models:
| Algorithm | 2008A improvement over 2007B |
| Primal | 50% |
| Dual | 27% |
| MIP | 45% |
