NEOS Server Home
Follow these steps to submit a job to NEOS via email or 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 email, send this file as the message body or as a plain text attachment to neos@neos-server.org. 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.

Note: keep in mind that the Gurobi solvers are not available via the XML-RPC interface. Please use the web submission form or submit your job via email.

Description of input values

model
To submit an optimization problem specified in the GAMS modeling language to the NEOS Server, you need to specify the the absolute path to the 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).
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.
wantgdx
Check the box to have the solver return a compressed GDX file that contains all of the symbols in the model.
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.
