Xpress Solveris the technology component that supports all of FICO's optimization solver technologies including:
- Xpress Optimizer: core engine comprises of LP (simplex and barrier), MIP, (MI)QP, (MI)QCQP, and (MI)SOCP solvers. It also provides core services, like the tuner, to other components.
- Xpress Nonlinear: provides successive linear programming and an interior point solver for nonlinear problems, integrating closely with the Optimizer’s MIP framework.
- Xpress Global: provides an engine for solving nonlinear problems to global optimality integrating with the components of Xpress Nonlinear and Xpress Optimizer.
- Xpress Kalis: provides constraint-based programming capabilities. Combined with the optimizer, it can make use of MIP relaxations of the CP problem.
- FICO Xpress 9.7 is available as part of Docker images on Docker Hub. Users are requested to read the licensing terms.
- Python users are recommended to use this image.
- For other Xpress APIs, users can get started from this image.
- Improved Windows installers including a new option to install Xpress in an automated manner on Windows via the command line in silent headless mode.
