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
