Gurobi

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/AMPL


The user must submit a model in AMPL format. Examples are provided in the examples section of the AMPL website.

The problem must be specified in a model file. A data file and commands files may also be provided. If the commands file is specified, it must contain the AMPL solve command; however, it must not contain the model or data commands. The model and data files are renamed internally by NEOS.

The commands file may include option settings for the solver. To specify solver options, add 

  option gurobi_options 'OPTIONS';
where OPTIONS is a list of one or more of the available solver options for AMPL.
