The NEOS Server offers the Gurobi Optimizer for the solution of linear programming (LP) problems, mixed-integer linear programming (MILP) problems, and second-order conic programming (SOCP) problems. LPs and MILPs can be submitted to Gurobi on the NEOS server in AMPL, GAMS, LP, or MPS format. SOCPs can be submitted in AMPL, GAMS or NL 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 for Gurobi/LP

To solve a 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.

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.
