Follow these steps to submit a job to NEOS via XML-RPC clients:
  1. Save the following template using your browser's copy and paste tools
  2. Using your favorite editor, plug your data files and parameters into the message in the indicated spots
  3. 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.
  4. 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 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
Upload the GAMS model file.
options
The solver options file is optional. If provided, the statement <modelname>.optfile = 1 ; is required before the solve statement in your model file. Only optfile = 1 is supported, however, options also may be specified within the model input file (see the GAMS documentation).
parameters
A secondary parameters file may be uploaded to NEOS. This file is optional. Note that some settings are overwritten by NEOS default settings. (See GAMS Call and CL Parameters for more details.)
gdx
Optional GDX file for inputs. This file will be renamed to "in.gdx". The model must include "$GDXIN in.gdx" to load this file.
restart
A GAMS restart file can be submitted to NEOS. (See GAMS Save and Restart for more details.)
wantgdx
Check the box to have the solver return a compressed GDX file that contains all of the symbols in the model.
wantlst
Check the box to include the GAMS listing file in returned output.
wantlog
The log file contains information generated by the algorithm during a solve. Check the box to have the log file included in the output returned.
comments
Enter any additional comments here (e.g. to identify the data for your own information). These comments will be returned with your results.
