Abstract

This paper is a preliminary study of the types of collective behavior tasks that are best solved by Neuro-Evolution (NE). This research tests a hypothesis that for a multi-rover task, the best approach (for deriving effective collective behaviors) is to evolve complete Artificial Neural Network (ANN) controllers, and then combine controller behaviors in a collective behavior context. Such methods are called multi-agent Conventional Neuro-Evolution (Multi-Agent CNE). This is opposed to methods such as Enforced Sub-Populations (ESP) which evolves individual neurons and then combines them to form complete ANN controllers. Single and multi-agent CNE and ESP approaches to evolving collective behavior solutions are tested comparatively in the multi-rover task. The multi-rover task requires that teams of rovers (controllers) cooperate in order to detect features of interest in a virtual environment. Results indicate that a Multi-Agent CNE approach derives rover teams with a higher task performance and genotype diversity, comparative to ESP.
