John .... Here are the references. If you
want to continue this discussion with
experts, I can put you in contact with Alfred
Hubler himself. Glad to be of help.

>From Prediction and Adaptation in an
Evolving Chaotic Environment by Alfred
Hubler and David Pines in Cowan, , Pines, and

ABSTRACT: We describe work in progress on
computer simulations of adaptive predictive
agents responding in a chaotic environment
and to one another. Our simulations are
designed to quantify adaptation and to
explore coadaptation for a simple calculable
model of a complex adaptive system. We first
consider the ability of a single agent,
exposed to a chaotic environment, to model,
control, and predict the future states of
that environment. We then introduce a second
agent which, in attempting to model and
control both the environment and the first
agent, modifies the extent to which that
agent can identify patterns and exercise
control. The competition between the two
predictive agents can lead to either chaos,
or to metastable emergent behavior , best
described as a leader-follower relationship.
Our results suggest a correlation between
optimal adaptation, optimal complexity, and
emergent behavior, and provide preliminary
support for the concept of optimal
coadaptation near the edge of chaos.
