Frequently Asked Questions More about the NEOS Server Credits AMPL and the NEOS Server AMPL users have the opportunity to compare alternative optimization methods for an application, by taking advantage of the large and growing collection of solvers for which AMPL interfaces are available. This opportunity can be more apparent than real, however, when considerable time and cost are required to separately obtain and install each solver to be tested. These services are available free of charge to anyone who has the requisite Internet connections. Remote solvers available The following solvers are currently available for use through either of the AMPL Remote Access interfaces described below. For more information, follow the links from the solver names to their entries in the NEOS Optimization Software Guide .
Additional solvers are to be provided.
The NEOS Server also executes the requested solver. AMPL's display or printing commands can be included in the run file to produce listings of results that are sent back along with other AMPL output. To use this facility, follow a link below to consult the page of instructions for the solver in which you are interested. Included in the instructions are directions for sending your files to the NEOS Server. E-mail submission, using a specified format for which a template is provided Web submission, by giving a URL for each file Additional methods and interfaces are under development.
