Whats New in SAS Optimization.jpg

 

Hi SAS Optimization Community,

I’m presenting a live “Ask the Expert” webinar on May 23rd, 11 AM – 12 PM ET entitled What’s New in SAS Optimization? I’ll show you how SAS Optimization continues to improve on its powerful modeling language with unified access to a broad suite of solvers. Bring your questions. We’ll host a live Q&A session at the end of the webinar.

 

You will learn about:

  • All the ways SAS Optimization is changing.
  • Recently added features, including a conic optimization solver and an automated Benders decomposition algorithm.
  • SAS Optimization performance improvements.

Reserve your spot for the webinar.

Hello Rob,

Thanks so much for the great presentation you gave yesterday.

Could you share the SAS code you used during your demo?

Hi Ethan,

 

I'm glad you enjoyed the presentation.  Attached is a .zip file that contains the three .sas files and one .sasnb file.  Please let me know if you have any further questions.

 

Thanks,

Rob

Hi Rob,

It doesn't work when running your code given my SAS/OR 15.2 on 9.4 M7 with ETS.

Below is my SAS log.

 

Any idea?

 

thanks,

Ethan

Yes, that is expected behavior.  The Benders decomposition algorithm is a new feature in SAS Viya 2024.05, just released last week.
