NEOS Interfaces to Gurobi

Sample Submissions


The NEOS Server offers the Gurobi Optimizer for the solution of linear programming (LP) problems, global (GO) 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/NL

The user must submit a model in NL format. The NEOS Server will automatically handle an NL model in either binary or text format. NL files in either format can additionally be zipped, gzipped, or tarred prior to submission if desired.

An options file can optionally be specified. Please note that certain options may be restricted, altered, or removed by the NEOS server prior to solving. For example, users are limited to a max of four solver threads -- requests for more threads in the options file will not be honored.

Note: Gurobi NEOS solvers are not accessible via the XML-RPC interface. Please use this web submission form or our email interface.
