Operating System and Hardware

The following are the supported platform, operating system, and processor combinations for FICO Xpress.

Xpress Solver - Xpress Optimizer and Xpress Nonlinear

Xpress Solver is the framework that supports all of FICO's optimization solver technologies, including Xpress Optimizer and Xpress Nonlinear.

These can be used within our modeling language Xpress Mosel or directly from Python.

Python Support

Xpress Solver (Xpress Optimizer and the Nonlinear solvers) can be used with the following Python versions.

Xpress Mosel

The Xpress Mosel language allows the user to define his models in a form that is close to algebraic notation and to solve them in the same environment.

It interfaces to statistics packages such as R or Matlab. Mosel provides a module python3.dso that implements functionality for exchanging data between a Mosel model and Python 3 (C Python) and for calling Python 3 scripts.

• Xpress Workbench is the premier choice as IDE (Integrated Development Environment) for standalone Mosel models and Xpress Insight apps. It integrates with Insight for remote debugging
• Xpress IVE is deprecated but still available for Mosel on Windows only.
• Mosel connectivity to spreadsheets is available on Windows, Linux, and macOS.

Python Support

Mosel provides a module python3.dso that implements functionality for exchanging data between a Mosel model and Python 3 (CPython) and for calling Python 3 scripts. The Mosel run-time library loads and runs the Python interpreter. Xpress Mosel can be used with the following Python versions:

• Python 3.4.3 to Python 3.7.5

R support

The R interface for Xpress Mosel makes it possible to easily exchange data with R and execute R scripts, or evaluate expressions in the R language, from within a Mosel model.

• Mosel supports R versions 3.0 to 3.6.x

Data Sources

Mosel can connect to data in memory through files, databases and web services. It connects to any ODBC-enabled data source, has a specific Oracle driver and drivers for Excel, CSV, XML, JSON as well as its own DAT format. Users can implement custom drivers and use Mosel's free form reading and writing capabilities.

Xpress Solver - Xpress Kalis

Xpress Kalis provides access to the Artelys Kalis Constraint Programming (CP) solver from a Mosel module allowing the user to formulate and solve CP models in the Mosel language.

Xpress Kalis combines a finite domain solver and a solver over continuous (floating point) variables. All data handling facilities of the Mosel environment, including data transfer in memory and ODBC access to databases can be used with Xpress Kalis.
