abstract: 'Several attempts have been made in the past to construct encoding schemes that allow modularity  to emerge in evolving systems, but success is limited.  We believe that in order to create successful and scalable encodings for emerging modularity, we first need to explore the benefits of different  types of modularity by hard-wiring these into evolvable systems. In this paper we explore different ways of exploiting sensory symmetry inherent in the agent in the simple game Cellz by evolving symmetrically identical modules. It is concluded that significant increases in both speed of evolution and final fitness can be achieved relative to monolithic  controllers. Furthermore, we show that a simple function approximation task that exhibits sensory symmetry can be used as a quick approximate measure of the utility of an encoding scheme for the more complex game-playing task.'
