The NEOS Server offers Gurobi for the solution of mixed integer programming problems that can be modeled in LP format.

Using the NEOS Server with LP/Gurobi

To solve a mixed integer linear programming problem using LP as input, you need only submit the LP file. The LP file may be submitted in gzipped or zipped format, and NEOS will automatically uncompress it for you. (This may be handy if the LP file is large).

The model is specified by an LP file, and optionally a parameter file. The parameter file should consist of lines of the format
Keyword Value
where Keyword is one of the Gurobi Parameter keywords, and Value is the value to which you wish to set the parameter.
