Options
The table below describes the options available for GeneticSearch.
Option |
Description |
|---|---|
crossoverProb |
Set the probability of crossover. This is the probability that two population members will exchange genetic material. |
maxGenerations |
Set the number of generations to evaluate. |
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. Default is equal to the number of generations meaning that a report will be printed for initial and final generations. Setting the value to 5 will result in a report being printed every 5 generations. |
seed |
Set the random seed. |
startSet |
Set a start point for the search. This is specified as a comma seperated list off attribute indexes starting at 1. It can include ranges. Eg. 1,2,5-9,17. The start set becomes one of the population members of the initial population. |
