  abstract =     "An investigation into the conditions conducive to the
                 emergence of heterogeneity among agents is presented.
                 This is done by using a model of creative artificial
                 agents to investigate some of the possibilities. The
                 simulation is based on Brian Arthur's 'El Farol Bar'
                 model but extended so that the agents also learn and
                 communicate. The learning and communication is
                 implemented using an evolutionary process acting upon a
                 population of strategies inside each agent. This
                 evolutionary learning process is based on a Genetic
                 Programming algorithm. This is chosen to make the
                 agents as creative as possible and thus allow the
                 outside edge of the simulation trajectory to be
                 explored. 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 qualitatively
                 different roles. It provides some evidence that the
                 introduction of a flexible learning process and an
                 expressive internal representation has facilitated the
                 emergence of this heterogeneity.",
