The Use of Linkage Learning in Genetic Algorithms By David Newman

Genetic Algorithms: Recap Search Algorithm that uses Mechanisms of Natural Selection –Parameter Sets (Genomes) have Fitness Values –Higher Fitness Value = Higher Probability of Selection Selected Genomes used to produce Next Generation –Directly Copied –Mutation –Crossover between Two Genomes –Mutation & Crossover

Linkage Learning Why Learn Linkage? –Reduces the Probability that sets of Functional Dependent Values are split up when Crossover is performed What is Linkage Learning? –The Ability to Learn Functional Dependency between Genes How is Linkage Learnt? –Improving Genetic Linkage Distance between Functionally Dependent Genes –Store Functionally Dependent Relationships
