Abstract
we propose that learning complex behaviours can be
achieved in a coevolutionary environment where one
population consists of the human users of an
interactive adaptive software tool and the
öpposing" population is artificial, generated by a
coevolutionary learning engine. We take advantage of
the Internet, a connected community where people and
software coexist. A new kind of adaptive agent can
exploit its interactions with thousands of users-inside
a virtual "niche"-to learn in a coevolutionary
human-robot arms race. Our model is Tron, a simple
dynamic game where introspective self-play quickly
leads to collusive stagnation. We describe an
application where thousands of small programs are sent
to play with people through the Java interpreter
running in their web browsers. The feedback provided by
these agents is collected in our server and used to
augment an ever improving fitness landscape for local
robot-robot games. Speciation and fitness sharing
provide diversity to challenge humans with a variety of
differ ent strategies. In this way, we obtain an
evolving environment where human as well as artificial
adaptation are simultaneously taking place.
