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@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.

par
You can also submit a parameter file, in Xpress-MP's format, if you wish to override the default parameter settings.
(Your file will be scanned for settings that do not conform to our operational policy for this solver. The possibly modified file will be returned with your output.)
maximize
You may specify that your objective should be maximized (the default is minimization).
nosol
You may specify whether your solution should be included or suppressed (the default is to include the solution).
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.
comments
>Enter any additional comments here (e.g. to identify the data for your own information.) These comments will be returned with your results.
