NAME

  Mutation - BitFlip mutation, changes several bits, depending on the probability

SYNOPSIS

  my $xmlStr=<<EOC;
  <op name='Mutation' type='unary' rate='2'>
    <param name='probability' value='0.5' />
  </op>
  EOC
  my $ref = XMLin($xmlStr);

  my $op = OpBase->fromXML( $ref );
  print $op->asXML(), "\n*Arity ->", $op->arity(), "\n";

  my $op = new Mutation (0.5 ); #Create from scratch

Base Class

OpBase

DESCRIPTION

Mutation operator for a GA

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

set

Sets the instance variables. Takes a ref-to-hash as input

apply

Applies mutation operator to a ``Chromosome'', a bitstring, really. Can be applied only to victims with the _str instance variable; but it checks before application that both operands are of type BinaryIndi.

asXML

Prints as XML, following the EvoSpec 0.2 XML specification. Should be called from derived classes, not by itself.
