NEOS Server

The NEOS Server is an Internet-based client-server application that provides free access to a library of optimization solvers.

Most of the solvers are hosted by the University of Wisconsin in Madison, where jobs run on a cluster of high-performance machines managed by the HTCondor software.

The server was developed in 1996 by the Optimization Technology Center of Argonne National Laboratory and Northwestern University.

Jobs can be submitted via a web page, email, XML RPC, Kestrel[7] or indirectly via third party submission tools SolverStudio for Excel, OpenSolver, Pyomo, JuMP (through the Julia package NEOS[8]) and the R package rneos.
