NAME

Algorithm::Evolutionary::Op::String_Mutation - Bit-flip mutation

SYNOPSIS

my $xmlStr2=<<EOC; #howMany should be integer
<op name='String_Mutation' 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::String_Mutation 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 string; does not need a rate

METHODS

new( [$how_many] [,$priority] )

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( $chromosome )

Applies mutation operator to a "Chromosome", a string, really.
