-
This class specifies the basic characteristics of a mutation operator. Its job is - to modify the connections and functions of the chromosome according to the operator's - parameters. -

- Parameters may be specified to control the implemented mutation. Any parameters - registered with registerParameters() should be displayed by the user interface, - if it is being used. See Module for more information. -

- It is advisable to use Resources.reportln() and Resources.report() - to print any relevant information. Note that reportln() and report() are affected - by the report interval base parameter. Use Resources.println() and - Resources.print() to print information regardless of the current generation. - See Resources for more information.

Percent point mutator -

- This operator calculates how many genes to mutate based on the mutation rate - parameter. The total number of genes is computed from the number of nodes, - the arity and the number of outputs. It then uses the point mutation - algorithm to perform the required number of mutations.
