NAME

Algorithm::Evolutionary::Op::Animated_GIF_Output - Creates an animated GIF, a frame per generation. Useful for binary strings.

SYNOPSIS

my $pp = new Algorithm::Evolutionary::Op::Animated_GIF_Output; 

my @pop;
my $length = 8;
my $number_of_strings = 10;
for ( 1..$number_of_strings ) {
  my $indi= new Algorithm::Evolutionary::Individual::String [0,1], $length;
  push @pop, $indi;
}

$pp->apply( \@pop );
my $options = { pixels_per_bit => 2,
                length => $length,
                number_of_strings => $number_of_strings };

$pp = new Algorithm::Evolutionary::Op::Animated_GIF_Output $options

$pp->apply( \@pop );
$pp->terminate();
my $output_gif = $pp->output(); # Prints final results

DESCRIPTION

Saves each generation as a frame in an animated GIF. Every individual gets a line of the number of pixels specified, and bits set to "1" are represented via black pixels or fat pixels. By default, a bit takes a single pixel.

INTERFACE

new( [$hash_ref] )

$hash_ref is a hashref with 3 options: pixels_per_bit, which defaults to 1, and length and number_of_strings which have no default and need to be set in advance to set up the GIF before any population individual is seen.

apply( $population_hashref )

Applies the single-member printing function to every population member

terminate()

Finish the setup of the animated GIF.

output()

Returns the animaged GIF; must be assigned to a variable.

INCOMPATIBILITIES

None reported.
