* Mainly fixing problems with Perl heuristics And also adding a little bit of text to the README file to help with local use and test. * Adds new sample * Adds a couple of samples more, not represented before * Moves installation intructions to CONTRIBUTING.md Refs #2309 and also changes github.com to an uniform capitalization. * Correcting error. Great job, CI * Moving another file * Adds samples and new checks for perl/perl6 * Stupid mistake * Changing regex for perl5 vs perl6 Initial suggestion by @pchaigno, slightly changed to eliminate false positives such as "classes" or "modules" at the beginning of a line in the =pod BTW, it would be interesting to just eliminate these areas for language detection. * Eliminates Rexfile from Perl6 And adds .pod6 * Followup to #2709 I just found I had this sitting here, so I might as well follow instructions to fix it. * Adds example for pod6 * Eliminates .pod because it's its own language * Removes bad directory * Reverting changes that were already there * Restored CONTRIBUTING.md from head I see installation of cmake is advised in README.md * Eliminates `.pod6` To leave way for #3366 or succeeding PRs. * Removed by request, since we're no longer adding this extension * Sorting by alphabetical order filenames * Moved from sample to test fixtures

=head1 NAME
|
|
|
|
Algorithm::Evolutionary::Fitness::Any - Façade for any function so that it can be used as fitness
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use Algorithm::Evolutionary::Utils qw( string_decode )
|
|
|
|
sub squares {
|
|
my $chrom = shift;
|
|
my @values = string_decode( $chrom, 10, -1, 1 );
|
|
return $values[0] * $values[1];
|
|
}
|
|
|
|
my $any_eval = new Algorithm::Evolutionary::Fitness::Any \&squares;
|
|
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Turns any subroutine or closure into a fitness function. Useful mainly
|
|
if you want results cached; it's not really needed otherwise.

Applies the instantiated problem to a chromosome. It is actually a

wrapper around C<_apply>.

This is the one that really does the stuff. It applies the defined

function to each individual. Itis cached for efficiency.
