The NEOS Server offers the Gurobi Optimizer for the solution of linear programming (LP) problems that can be modeled in LP format. The Gurobi Optimizer is a state-of-the-art solver for mathematical programming. The solvers in the Gurobi Optimizer were designed from the ground up to exploit modern architectures and multi-core processors. For more information on Gurobi products and services, see the Gurobi website.

Using the NEOS Server with LP/Gurobi

To solve an LP 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.

The LP problem must be specified by an LP file. An optional parameter file may also be specified. This file should consist of lines in the format
Keyword Value
where Keyword is one of the Gurobi parameter keywords and Value is the value of the parameter.
