Option

Description

crossoverProb

Set the probability of crossover. This is th= e probability that two population members will exchange genetic material. <= /p>

maxGenerations

Set the number of generations to evaluate. <= /p>

mutationProb

Set the probability of mutation occuring.

populationSize

Set the population size. This is the number = of individuals (attribute sets) in the population.

reportFrequency

Set how frequently reports are generated. De= fault is equal to the number of generations meaning that a report will be p= rinted for initial and final generations. Setting the value to 5 will resul= t in a report being printed every 5 generations.

seed

Set the random seed.

startSet

Set a start point for the search. This is sp= ecified as a comma seperated list off attribute indexes starting at 1. It c= an include ranges. Eg. 1,2,5-9,17. The start set becomes one of the populat= ion members of the initial population.
