Ants War with Evolutive Pheromone Style Communication

This paper is concerned about the origin of pheromone communication in complex societies, e.g., colonies of real ants and bees. The aim of the work is to study whether pheromone communication among artificial ant agents in a cooperative foraging scenario can arise simply by letting selection favor successfully foraging genotypes. For such aim, we introduce the ants war in which ant agents foraging more food items than the opponent can survive to next generation. In the experiments, we confirmed the emergence of pheromone communication without a specific predefined one.
