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. date: 1998 date_type: published refereed: FALSE citation: Edmonds, Bruce (1998) Gossip, Sexual Recombination and the El Farol Bar: modelling the emergence of heterogeneity.
