= Island Offspring Selection Genetic Algorithm = '''Algorithm Parameters:''' ||= Parameter =||= Description =|| || Analyzer || The operator used to analyze each generation. || || !ComparisonFactorLowerBound || The lower bound of the comparison factor (start). || || !ComparisonFactorModifier || The operator used to modify the comparison factor. || || !ComparisonFactorUpperBound || The upper bound of the comparison factor (end). || || Crossover || The operator used to cross solutions. || || Elites || The numer of elite solutions which are kept in each generation. || || !EmigrantsSelector || Selects the individuals that will be migrated. || || !ImmigrationReplacer || Replaces part of the original population with the immigrants. || || IslandAnalyzer || The operator used to analyze each island. || || !MaximumGenerations || The maximum number of generations which should be processed. || || !MaximumSelectionPressure || The maximum selection pressure that terminates the algorithm. || || !MigrationInterval || The number of generations that should pass between migration phases. || || !MigrationRate || The proportion of individuals that should migrate between the islands. || || Migrator || The migration strategy. || || !MutationProbability || The probability that the mutation operator is applied on a solution. || || Mutator || The operator used to mutate solutions. || || !NumberOfIslands || The number of islands. || || !OffspringSelectionBeforeMutation || True if the offspring selection step should be applied before mutation, false if it should be applied after mutation. || || Population Size || The size of the population of solutions. || || Seed || The random seed used to initialize the new pseudo random number generator. || || !SelectedParents || How much parents should be selected each time the offspring selection step is performed until the population is filled. || || Selector || The operator used to select solutions for reproduction. || || !SetSeedRandomly || True if the random seed should be set to a random value, otherwise false. || || !SuccessRatio || The ratio of successful to total children that should be achieved. || '''Remarks:''' * ''SelectedParents:'' This parameter should be about the same or twice the size of PopulationSize for smaller problems, and less for large problems.
