NEOS Interfaces to FICO-Xpress

WWW Form & Sample Submissions


The NEOS Server offers FICO Xpress for the solution of mixed-integer linear programming (MILP) problems that can be modeled in MPS format. To learn more about the FICO Xpress Optimization Suite, visit the FICO Optimization website.

Using the NEOS Server with FICO Xpress

The user must submit a model in MPS format to solve an MILP problem. 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 line <email></email> to the XML file that is submitted to NEOS.
