Concurrent and Distributed NARS

[djire...@gmail.com]

Hi everybody,

I've been experimenting with NARS running on the BEAM virtual machine and using the Erlang's Open Telecom Platform (OTP). 

This  gives concurrency and distributed computing (along with fault tolerance) out-of-the-box (of course not without it's own problems). 

I was thinking about writing it up for the next AGI Conf 2026, but wondered if there were any other attempts at a concurrent / distributed NARS I could refer to. I recall there were at least 50 implementations (from a slide presented by someone else) but couldn't find any distributed implementations nor were they mentions in this google group. 

I was considering to heavily cite  "The Event Buffer of OpenNARS" paper which had a parallel architecture to it. 

Appreciate any thoughts. 

Regards,

David

Hi David,

The relevant works I can think of at the moment:

• Intelligent Multiagent Systems based on Distributed Non-Axiomatic Reasoning
• https://github.com/rasom/opennars2

There have been discussions and experiments on multi-agent cooperation and hardware acceleration for OpenNARS and ONA; however, I have not found any publicly available writing or code.

Looking forward to your results!

Regards,

Pei

Thanks Pei.  I hadn't seen Dejan Mitrovic's thesis.

Hi David!

The most advanced distributed NARS implementation so far is Tony Lofthouse's ALANN2018, which scales NARS (NAL-1 to NAL-6) to thousands of threads operating concurrently on shared concept memory with high efficiency: https://github.com/opennars/ALANN2018

However, temporal and procedural reasoning are much harder to handle in a distributed architecture, and ALANN2018 did not address them. More generally, these aspects have also long been the weakest parts of NARS conceptually, not just implementation-wise, with many missing and underspecified ideas, making embodied NARS-based divert far from AGI expectations.

I recently tried to push beyond ONA's sensorimotor capabilities, with some success, focusing on improved temporal and event-stream reasoning but with NAL1-8 support: https://github.com/patham9/estream

While limited, NAL-based sensorimotor can still be useful though, as it can allow agents to adapt very effectively when event encodings are at the right abstraction level.

Best regards,

Patrick

Hi Patrick,

Thanks! I've been meaning to read Tony's book. 

Am I right in assuming the temporal issues in a distributed cluster are because it would be incredibly difficult to synchronise a time stamp? 

Are you also able to elaborate on some of the other weaker aspects?

Thanks.

Regards,

David
