Abstract

We explore how information theoretic quantities
such as potential information flow (empowerment) can be used
as a drive toward complex collective behaviour in the context
of multi-agent systems. In a first experiment, we investigate
the empowerment of two agents interacting in a grid world.
We show that some conditions lead to higher empowerment
than others, depending on the amount of interaction and the
amount of information shared by the agents. We then investigate
more deeply the tradeoff between freedom of the agents and the
constraints they impose on each other. We show that there exist a
trade-off between these where empowerment is maximized. In a
third experiment, we show that agents behaving so as to maximize
potential information transfer over time generate a wide range of
complex collective behaviours. We then discuss how these notions
can be compared to what happens in natural systems.
