In Algorithm::Evolve, the first group of options is implemented by the user 
for maximum flexibility. These functions are abstracted to class of evolvable
objects (a B<critter class> in this document). The module itself handles the
representation-independent parts of the algorithm using simple configuration
switches and methods.

=head1 USAGE

If you're of the ilk that prefers to learn things hands-on, you should
probably stop here and look at the contents of the F<examples/> directory
first. 

=head2 Designing a class of critter objects (interface specification)

Algorithm::Evolve maintains a population of critter objects to be evolved. You 
may evolve any type of objects you want, provided the class supplies the 
following methods:

=over

lib/Algorithm/Evolve.pm  view on Meta::CPAN

This method is used for L</Co_Evolution|co-evolution> with the gladitorial
selection method. It should return a number less than zero if $critter1 is
"better," 0 if the two are equal, or a number greater than zero if $critter2
is "better." 

=back

You may also want to use the C<DESTROY> method as a hook for detecting when
critters are removed from the population.

See the F<examples/> directory for example critter classes. Also, take a look
at L<Algorithm::Evolve::Util> which provides some useful utilities for 
implementing a critter class.

        ...
    );

See the source of this module to see how the various selection/replacement
methods are implemented.
The mechanism for adding additional selection/replacement methods may change
in future versions.

Returns a random gene of the given size over the given alphabet, defaulting to
{0,1}.

L<Algorithm::Evolve|Algorithm::Evolve>

F<StringEvolver.pm> in the F<examples/> directory uses the utilities in
Algorithm::Evolve::Util to implement a completely generic simple string
evolver critter class in very few lines of code.
