Follow these steps to submit a job to NEOS via email or XML-RPC clients:
- Save the following template using your browser's copy and paste tools
- Using your favorite editor, plug your
data files and parameters into the message in the indicated spots
- Descriptions of the input are written with the web interface in mind.
If the description asks for the name of a file, then you will instead need
to insert the contents of the file itself.
- The
<![CDATA[ ... ]]> tag is an escape indicator. This
will ensure that any special characters in your inputs (such as <, >,
&, etc.) will be interpreted correctly.
For email, send this file as the message body or as a plain text attachment to neos@mcs.anl.gov. Do not send .doc, .rtf, .xsw, or other files that aren't plain text. The job results will be mailed to you.
For XML-RPC, you need to submit the contents of this file to NEOS with the
submitJob() method, and retrieve the results with the getResults() method. Go here for more information on using the XML-RPC interface to NEOS.

Description of input values
model
You can submit an optimization problem specified in the GAMS
modeling language to be solved using the optimization tools on
the NEOS Server. You need to specify the absolute path to a
GAMS file on your system.
options
The Options file is optional and requires that the
statement <modelname>.optfile = 1 ;
exist before the solve statement in your model file. At this
time, only optfile = 1 is supported; however,
options may also be specified within the model input file (see
the GAMS documentation).
wantlog
The log file contains information generated by the algorithm
during a solve. Checking the box will cause the log file to be
included in the output returned.
xpressemail
An email address is required for any submissions
to XPRESS solvers. This email address will be forwarded to Dash Associates
and may be used by Dash Optimization for promotional purposes.
NEOS results will not be sent to this address.

for your own information). These comments will be returned
with your results.
