The NEOS Server offers CONOPT for the solution of nonlinearly constrained
optimization problems in
CONOPT is a feasible path method based on the GRG algorithm. CONOPT is well
suited for models with very non-linear constraints. It is a fast method for
finding a first feasible solution that is particularly well suited for models
with few degrees of freedom. Also, if you have a model where many equations
can be solved one by one, CONOPT will take advantage of this property.
Similarly, intermediate variables only used to define objective function
terms are eliminated from the model and the constraints are moved into
the objective function.

Using the NEOS Server for CONOPT
The user must submit a model in
