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.
