NEOS Interfaces to FICO-Xpress

Sample Submissions


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.

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.
Check the box if your objective should be maximized. The default is minimization.
Suppress solution in results
Check the box if the solution should not be included in the output. The default setting is to include the solution.
