NEOS Interfaces to FICO-Xpress

Sample Submissions
WWW Form - Email - XML-RPC


The NEOS Server offers FICO Xpress for the solution of mixed-integer linear programming (MILP), linear programming (LP), second-order conic programming (SOCP), and nonlinear programming (NLP) 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/MPS

The user must submit a model in MPS format. The user may optionally specify a file that includes FICO Xpress commands to customize the use of the optimizer.

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:

Web Submission Form
Enter the location of the MPS file (local file)
Enter the location of the FICO Xpress parameter file
To override the default parameter settings, submit a parameter file in the FICO Xpress Optimizer format. The file will be scanned for settings that are not available on NEOS; the possibly modified file will be returned with the output.
Select the SIMPLEX or BARRIER algorithm.
