NAME

    Algorithm::Evolutionary::Op::Easy - evolutionary algorithm, single generation, with 
                    variable operators.


SYNOPSIS

  my $easyEA = Algorithm::Evolutionary::Op::Base->fromXML( $ref->{initial}{section}{pop}{op} );
  # Parsed XML fragment, see samples
  for ( my $i = 0; $i < $ref->{initial}{section}{pop}{op}{param}{maxgen}{value}; $i++ ) {
    print "<", "="x 20, "Generation $i", "="x 20, ">\n"; 
    $easyEA->apply(\@pop ); 
    for ( @pop ) { 
      print $_->asString, "\n"; 
    } 
  }
  #Define a default algorithm with predefined evaluation function,
  #Mutation and crossover. Default selection rate ls 4
  my $algo = new Algorithm::Evolutionary::Op::Easy( $eval );
  #Define an easy single-generation algorithm with predefined mutation and crossover
  my $m = new Algorithm::Evolutionary::Op::Bitflip; #Changes a single bit
  my $c = new Algorithm::Evolutionary::Op::Crossover; #Classical 2-point crossover
  my $generation = new Algorithm::Evolutionary::Op::Easy( $rr, 0.2, [$m, $c] );


Base Class

Algorithm::Evolutionary::Op::Base


DESCRIPTION

Genetic algorithm that uses the other component. Must take as input the operators thar are going to be used, along with its priorities


METHODS

new

Creates an algorithm, with the usual operators. Includes a default mutation and crossover, in case they are not passed as parameters

set

Sets the instance variables. Takes a ref-to-hash as input

apply

Applies the algorithm to the population; checks that it receives a ref-to-array as input, croaks if it does not. Returns a sorted, culled, evaluated population for next generation.
