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

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.

The problem must be specified in a model file. A data file and commands
files may also be provided. If the commands file is specified, it must
contain the AMPL solve command; however, it must not contain
the model or data commands. The model and data
files are renamed internally by NEOS.
The commands file may include option settings for the solver. To specify
solver options, add
option nsips_options 'OPTIONS';
