Models of Evaluation and Learning Lamarckian Evolution –Evolution over many generations was directly influenced by the experiences of a individual organisms during their lifetime. –Current scientific evidence contradicts it. –For current computer study, it sometimes improves the effectiveness of GAs. Baldwin Effect –If a species is evolving in a changing environment, there will be evolutionary pressure to favor individuals with the capability to learn during their lifetime. –It increases survivability and genetic diversity of the species. Parallelizing Genetic Algorithms –GAs are naturally suited to parallel implementation. –Coarse grain –Fine grain
