Listed below are the available solvers organized by problem type. If you need help in selecting a solver, consult the Optimization Tree of the NEOS Guide. The choice of solver then determines the available input options for defining the optimization problem.

Each solver has sample problems and background information on the solver. Be sure to submit a sample problem to get a feel for how to submit optimization problems to NEOS. If you encounter problems, consult the NEOS Server FAQ, or contact us by clicking on the Comments and Questions link at the bottom of the page.
