Finding unique feedback loops

Hi,

I know there is a Loops button to find feedback loops going through a single variable.

But is it possible to find all unique feedback loops that exist in a model, going through all variables but counting each loop only once?

Thanks,
Kaveh.

No. Even for small models, the number of loops can run into millions.

However, this is an area of active development, using the shortest independent loop set methodology originated by Kampmann and developed by a number of others in the SD literature.

Hi Admin and Tomfid,

I am looking through SILS for the first time. I see the help button redirecting to Oliva's page with publications. In reading, I feel like I need a better foundational understanding of the EEA from Forrester 1984 and SILS from Oliva 2004. Are there any recommendations on where to start with this? I am reading some elaborations and challenges to Oliva, but these tend to be written under the assumption that SILS can and is already understood by the reader. Any suggestions for a simple explainer article to start?
