A virtual creatures model for studies in artificial evolution

Channon

Abstract

We present the results of our replication of Karl Sims' work on the evolution of artificial creatures in a physically realistic 3D environment. We used standard McCulloch-Pitts neurons instead of a more complex set of ad hoc neurons, which we believe makes our model a more general tool for future experiments in artificial (co-)evolution. We provide a detailed description of our model and freely accessible source code. We describe our results both qualitatively and quantitatively, including an analysis of some evolved neural controllers. To the. best of our knowledge, our work is the first replication of Sims' efforts to achieve results comparable to Sims' in efficiency and complexity, with standard neurons and realistic Newtonian physics.
