public abstract class Mutator

+
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.
