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.

| 10.15 (Catalina) |
|
In addition, access to an Xpress Insight 5 server is required.
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:
| Note The Mosel module python3.dso cannot be used with Python 3.8.0 |
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 4.1.x
| Note Download the version of R from the R Project web site at www.r-project.org, targeting the same platform as Mosel. Therefore, if you have Windows 64-bit Mosel installed, download a matching R version. |
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.

Interfaces
Java
The interfaces for calling Xpress libraries from Java require a minimum of Java 7 (internal version: 1.7.0); compatible distributions of Oracle Java and OpenJDK are supported.
The Mosel module mosjvm works with Java 8 and 11. Distributions other than Oracle Java, OpenJDK, and Amazon Corretto are not supported.
.NET
The interfaces for calling Xpress Optimizer, BCL and Mosel libraries from .NET dual-target .NET Framework 3.5 and .NET Standard 2.0. They are available for Windows and Linux platforms only. Xpress .NET interfaces are not available on RHEL6.
The interfaces for calling Xpress NonLinear libraries from .NET target .NET Framework 3.5. They are available for Windows platforms only.
Knitro
On Linux platforms, the Knitro solver component requires libgfortran (version libgfortran.so.3) to be installed on the system.
