NAME ^

Algorithm::Evolutionary::Fitness::Trap - 'Trap' fitness function for evolutionary algorithms

SYNOPSIS ^

    my $number_of_bits = 5;
    my $a = $number_of_bits -1; # Usual default values follow
    my $b = $number_of_bits;
    my $z = $number_of_bits -1;
    my $trap = Algorithm::Evolutionary::Fitness::Trap->new( $number_of_bits, $a, $b, $z );

DESCRIPTION ^

Trap function act as "yucky" or deceptive for evolutionary algorithms; they "trap" population into going to easier, but local optima.

METHODS ^

new

Creates a new instance of the problem, with the said number of bits and peaks. Depending on the parameter value, might produce some errors and bail out, not all values are admissible.

_really_apply

Applies the instantiated problem to a chromosome

trap

Computes the value of the trap function
