NEOS Server Home

Welcome to the NEOS Server.

The NEOS (Network-Enabled Optimization System) Server is a free Internet-based service for solving optimization problems. The solvers available represent the state-of-the-art in optimization software. The NEOS Server offers a simple approach for solving a wide variety of optimization problems and provides several interfaces for accessing the solvers. After a user selects a solver and provides a description of the optimization problem, the NEOS Server determines the additional information required by the solver, links the optimization problem with the solver, and returns a solution upon completion.

To submit your optimization job, first click on the NEOS Solvers icon to find a suitable solver.
