FICO-Xpress

The NEOS Server offers FICO Xpress for the solution of mixed-integer linear programming (MILP), linear programming (LP), and second-order conic programming (SOCP) problems. Problems can be submitted to FICO Xpress on the NEOS server in AMPL, GAMS, MOSEL, or MPS format.

The FICO Xpress optimizer is a commercial solver for linear programming and mixed integer linear programming. XPRESS is part of the FICO Xpress Optimization Suite. To learn more about the FICO Xpress Optimization Suite, visit the FICO Optimization website.


Using the NEOS Server for FICO-Xpress/NL


The user must submit a model in NL format. The NEOS Server will automatically handle an NL model in either binary or text format. NL files in either format can additionally be zipped, gzipped, or tarred prior to submission if desired.

An options file can optionally be specified. Please note that certain options may be restricted, altered, or removed by the NEOS server prior to solving. For example, users are limited to a max of four solver threads -- requests for more threads in the options file will not be honored.

Note: An email address is required for any submissions to FICO Xpress solvers. This email address will be forwarded to FICO and may be used by FICO for promotional purposes. When using the XML-RPC interface, you must add the following line into the XML file that is submitted to NEOS:

<email>your.address@email.edu</email>
