Abstract

This paper presents a case for the value of “talkback” in genetic algorithms. Talkback is described in terms of an environmentally imprinted adaptation occurring at loci on the genotype, not expressed phenotypically but acting as control parameters for evolution. Motivations are presented drawing on examples of directed adaptation in nature and the field of optimised search. A model is described based on directed adaptation and the results of experiments, acting at the level of both the population and the individual, are presented.
