NAME

    Algorithm::Evolutionary::Individual::BitString - Classic bitstring individual for evolutionary computation; 
                 usually called I<chromosome>

SYNOPSIS

    use Algorithm::Evolutionary::Individual::BitString;

    my $indi = new Algorithm::Evolutionary::Individual::BitString 10 ; # Build random bitstring with length 10
                                   # Each element in the range 0 .. 1

    my $indi3 = new Algorithm::Evolutionary::Individual::BitString;
    $indi3->set( { length => 20 } );   #Sets values, but does not build the string
    
    $indi3->randomize(); #Creates a random bitstring with length as above
 
    print $indi3->Atom( 7 );       #Returns the value of the 7th character
    $indi3->Atom( 3 ) = 1;       #Sets the value

    $indi3->addAtom( 1 ); #Adds a new character to the bitstring at the end
    my $size = $indi3->size(); #Common interface to all individuals, should return 21

    my $indi4 = Algorithm::Evolutionary::Individual::BitString->fromString( '10110101');   #Creates an individual from that string

    my $indi5 = $indi4->clone(); #Creates a copy of the individual

    my @array = qw( 0 1 0 1 0 0 1 ); #Create a tied array
    tie my @vector, 'Algorithm::Evolutionary::Individual::BitString', @array;
    print tied( @vector )->asXML();

    print $indi3->asString(); #Prints the individual
    print $indi3->asXML() #Prints it as XML. See 
    print $indi3->as_yaml() #Change of convention, I know...

Base Class

Algorithm::Evolutionary::Individual::String

DESCRIPTION

Bitstring Individual for a Genetic Algorithm. Used, for instance, in a canonical GA

METHODS

new( $length )

Creates a new random bitstring individual, with fixed initial length, and uniform distribution of bits. Options as in Algorithm::Evolutionary::Individual::String

set( $hash )

Sets values of an individual; takes a hash as input. Keys are prepended an underscore and turn into instance variables
