The NEOS Server offers NSIPS for the solution of nonlinear semi-infinite
(SIP) programming problems in
AMPL format. The
infinite constraints are recognized by the solver as described in
NSIPS implements three classes of methods for the solution of nonlinear SIP
problems: three discretization methods, two penalty function approaches, and
a sequential quadratic programming (SQP) method. Nonlinear subproblems are

Using the NEOS Server for NSIPS
The user must submit a SIP problem in AMPL format, see the
Examples of such models can be found in the
SIPMOD database .
The model is specified by a model file, and optionally,
a data file, and a commands file.
If the command file is specified it must contain
the AMPL solve command.
The commands file may set options for NSIPS
by modifying the variable 'nsips_options'. See in this
user's guide on
how to pass options to the solver and
this list for
the available options.
