Algorithm::Evolutionary::Op::Bitflip - BitFlip mutation
            
          

SYNOPSIS

            

              
              
my $xmlStr2=<<EOC; #howMany should be integer
<op name='Bitflip' type='unary' rate='0.5' >
  <param name='howMany' value='2' /> 
</op>
EOC
my $ref2 = XMLin($xmlStr2);
my $op2 = Algorithm::Evolutionary::Op::Base->fromXML( $ref2 );
print $op2->asXML(), "\n*Arity ", $op->arity(), "\n";
my $op = new Algorithm::Evolutionary::Op::Bitflip 2; #Create from scratch with default rate
            
          

Base Class

Algorithm::Evolutionary::Op::Base

DESCRIPTION

Mutation operator for a GA; changes a single bit in the bitstring; does not need a rate

METHODS

new

Creates a new mutation operator with a bitflip application rate, which defaults to 0.5, and an operator application rate (general for all ops), which defaults to 1.

create

Creates a new mutation operator.

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 BitString.
