A Genetic Method for Evolutionary Agents in a Competitive Environment

A gene expression n-BDD is proposed in order to investigate co-evolutional environment. The gene expression is suitable for agent models to decide agent’s behavior using information from environment. We can apply genetic algorithm to evolve behavior of agents. In a quasi ecosystem, a herbivore, a carnivore and plants make a food chain, which is a typical competitive environment and causes co-evolution. A herbivore using an n-BDD more rapidly acquire its ability to survive from a carnivore than using finite state automaton. Moreover, in the environment which carnivores and herbivores are co-evolved, we have seen a food chain relation in an experimental field.
