  abstract =     "Brian Arthur's `El Farol Bar' model is extended so
                 that the agents also learn and communicate. The
                 learning and communication is implemented using an
                 evolutionary process acting upon a population of mental
                 models inside each agent. The evolutionary process is
                 based on a Genetic Programming algorithm. Each gene is
                 composed of two tree-structures: one to control its
                 action and one to determine its communication. A
                 detailed case-study from the simulations show how the
                 agents have differentiated so that by the end of the
                 run they had taken on very different roles. Thus the
                 introduction of a flexible learning process and an
                 expressive internal representation has allowed the
                 emergence of heterogeneity.
