Presentation Transcript

1. Genetic AlgorithmSearch and optimization method that mimics the natural selectionTerms to defineChromosome – a set of numbers representing one possible solutionGeneration – a single loop within GA loop searchLoops through the reproduction, mutation, and adaptation process to obtain best fit model

2. Genetic Operator - MutationEffects of MutationIntroduce variance to searchAid the search for global minimum by directing gradient search out of the local minimaMutation OperatorUniform Mutation – randomly replace with a new valueNon-uniform mutation – add or subtract a random value

3. Genetic Operator - CrossoverBenefits of CrossoverAid the search for elitesOptimize the search by keeping the optimal folding segmentsCrossover OperatorRandom 2-point Crossover – randomly exchange between parents 2 angles at a timeMultiple Entries Crossover – multiple random exchange

4. Genetic Operator - CrossoverCrossover OperatorBlending Poffspring = a Pmother +(1-a) Pfather

5. Genetic Operator - SelectionBenefits of SelectionAid the Elitism SearchSelection OperatorRanked Selection – higher the rank higher the probability of being chosenHigher rank or better fitnessLower rank or worse fitness

6. Genetic Operator - AdaptationAdaptation OperatorGradient search applied to each chromosomeBenefits of AdaptationProvide the local minima search
