NAME

Algorithm::Evolutionary::Op::GaussianMutation - Changes numeric chromosome components following the gaussian distribution.

SYNOPSIS

  my $op = new Algorithm::Evolutionary::Op::GaussianMutation( 0, 0.05) # With average 0, and 0.05 standard deviation

Base Class

Algorithm::Evolutionary::Op::Base

DESCRIPTION

Mutation operator for a GA: applies gaussian mutation to a number

new( [$average = 0] [, $standard deviation = 1] [, $rate = 1 ]

Creates a new mutation operator with an application rate. Rate defaults to 1.

create

Creates a new mutation operator with an application rate. Rate defaults to 0.1.

Called create to distinguish from the classwide ctor, new. It just makes simpler to create a Mutation Operator

apply( $chromosome )

Applies mutation operator to a "Chromosome", a vector of stuff, really. Can be applied only to victims with the _array instance variable; but it checks before application (roughly) that both operands are of type Algorithm::Evolutionary::Individual::Vector.
