Agent observation

[rhari008]

I would like to have the feature where agents can observe what other agents are doing. Currently with the kind of synchronous operations, I believe its not possible.

If I understand your request -- have you considered adjusting the scheduler?

Thanks for the response. Here is an example of what I requested:

There are two types of agents - Consumer and Provider. In stage 1, consumers are randomly paired with providers. A provider can either be good or bad. I want yet another type of agent introduced called the observer agent that can rate a provider by observing how it is serving a consumer.

Is this what you are looking for? https://mesa.readthedocs.io/en/stable/apis/time.html#mesa.time.StagedActivation

I explored that as well. Do you have an example, please?

But, this requirement needs the agents to be operated in parallel.

Edit: May be I can try pub sub model? Where a step of an observer agent gets activated on receiving a message.

I don't believe there is one. Can you submit a ticket?

With #2291 merged, this is straightforward to implement by a user if needed.
