[NEOS Support Req #254] Availability of MINLP (via AMPL) in NEOS
by Malcolm Irving 25 Aug '09

25 Aug '09

Dear Sir or Madam, We have been successfully using the MINLP solver in NEOS, via AMPL files, and have presented some of the results in a scientific journal paper. Recently, the availability of MINLP via this route has been intermittent. As the repeatability of our journal paper results is scientifically important we would like to understand the current and future availability of MINLP through NEOS. Has there been some recent problem which has now been resolved, and is the future availability determined? Many thanks for your attention. Yours sincerely, Prof. Malcolm R Irving Director - Brunel Institute of Power Systems School of Engineering and Design Brunel University Uxbridge UB8 3PH UK

Gulnara, I don't see any attached document, perhaps you could resend it. If your optimization problem is contained in one AMPL file, then you can send that as your model file and ignore the data and commands files.

[NEOS Support Req #248] Thank you!

Thank you for providing the NEOS server and optimization solvers. It is tremendously helpful and lets me test different ideas during my research rather painlessly. I have access to an optimization computer lab but using NEOS is so much easier and allows me to work on other things at the same time. Thanks again! Ed LTC Ed Chamberlayne, P.E.

[NEOS Support Req #247] Re: Minos timeout Job no. 1919995

Grham, If the web page times out, you can download the results from http://neos.mcs.anl.gov/neos/jobs/1919995.html (or whatever the job number is). The results will only be available for 5-7 days before being deleted.

[NEOS Support Req #246] Re: Fwd: NEOS Results for Job #1920085
by Jason Sarich 13 Aug '09

13 Aug '09

Leonid, the output for 1920085 is a very large file (200 MB) and the python is not handling it well. I have compressed it, you can download directly at http://neos.mcs.anl.gov/neos/jobs/1920085.html.gz When you send a compressed file, NEOS must convert it to ascii for proper handling which can add a bit to the file size.
