rateGT
Genome:
genomeTerminals: list of characters that are valid entries in a
chromosome for terminals (e.g.: variables in a regression problem).
genomeNonterminals: list of characters that are valid entries in a
chromosome for nonterminals (e.g.: operators in a regression problem).
genomeMaxArity: maximum arity operator in the nonterminal list.
Examples: boolean NOT has arity 1, arithmetic add has arity 2, boolean
IF has arity 3.
genomeNumGenes: number of genes in a chromosome.
genomeHeadLength: number of characters in the head of a gene. This is
used in combination with the maximum arity parameter to determine the
overall gene length.
genomeGeneConnector: nonterminal used to connect genes in a multi-gene
chromosome to form a single expression tree.
Genetic Operator Parameters:
maxISLen: Maximum length of insertion sequences.
maxRISLen: Maximum length of root insertion sequences.
Population Parameters:
populationSize: Number of individuals in the population per step.
numGenerations: How many generations to run algorithm for if maximum
fitness not achieved.
Fitness and selection:
maxFitness: Fitness of ideal individual.
rouletteExponent: Exponent for weight function used to determine
roulette wheel bin widths. Current default function is 1/(k^e) where
k is the bin number and e is the exponent.
selectionRange: Range of selection parameter (M) from the GEP paper.
