Abstract

Inspired upon the development of living systems, many models of artificial embryogeny are being proposed. These are usually aimed at the solution of some know limitations of evolutionary computation; among these scalability, flexibility and, more recently, fault-tolerance. This paper focuses on the latter, proposing an explanation of the intrinsic regenerative capabilities displayed by some models of multi-cellular development. Supported by the evidence collected from simulations, regeneration is shown to emerge as evolution converges to more regular regions of the genotype space. The conclusion is that intrinsic fault-tolerance emerges as evolution increases the evolvability of the development process.
