Free Webinar: What's New in SAS Optimization?

RobPratt — Tue, 21 May 2024 19:13:50 GMT

Hi SAS Optimization Community,

I’m presenting a live “Ask the Expert” webinar on May 23^rd, 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.

Want more tips? Be sure to subscribe to the Ask the Expert board to receive follow up Q&A, slides and recordings from this and other SAS Ask the Expert webinars.

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.
