Algorithm::Evolutionary::Op::Easy_MO - Multiobjecttive evolutionary algorithm, single generation, with
#Mutation and crossover. Default selection rate is 0.4
my $algo = new Algorithm::Evolutionary::Op::Easy_MO( $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_MO( $rr, 0.2, [$m, $c] );
Easy to use, single generation of an evolutionary algorithm. Takes
an arrayref of operators as input, or defines bitflip-mutation and
2-point crossover as default. The apply method applies a single
iteration of the algorithm to the population it takes as input
new( CW$eval_func, [$selection_rate,] [$operators_arrayref] )
Creates an algorithm that optimizes the handled fitness function and
reference to an array of operators. If this reference is null, an
array consisting of bitflip mutation and 2 point crossover is
generated. Which, of course, might not what you need in case you dont
have a binary chromosome. Take into account that in this case the
fitness function should return a reference to array.
set( CW$hashref, codehash, opshash )
Sets the instance variables. Takes a ref-to-hash (for options), codehash (for fitness) and opshash (for operators)
apply( CW$population )
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.
