NEOS Interfaces to proxy

WWW Form & Sample Submissions


The NEOS Server offers PROXY for the refinement of feasible solutions of mixed-integer linear optimization problems involving binary variables.

The proximity search algorithm was developed by Matteo Fischetti and Michele Monaci. PROXY uses the CPLEX library.

This solver was implemented by Hans Mittelmann and executes at under

Using the NEOS Server for PROXY

The user must submit a mixed-integer linear programming problem in one of two formats. When submitting via e-mail or XML-RPC delete empty tokens!
See this file for an explanation of PROXY and its use.
