Comparing Mechanisms for Evolving Evolvability
Workshop Paper, GECCO '99 Workshop, pp. 38 - 41, July, 1999
Abstract
In evolutionary search, the term evolvability as defined in [Altenberg 94] refers to ``the ability of a population to produce variants fitter than any yet existing''. In this paper, we examine a few existing mechanisms which provide the potential for the evolvability of a population to itself evolve. One key property that we identify among such mechanisms is a many-to-one genotype-to-phenotype mapping, which permits variations in evolvability to occur independent of fitness. Another is the propensity for individuals to become increasingly conservative in parent-offspring transmission as they become more fit, a phenomenon which becomes stronger as selection pressure becomes weaker.
