| Description | | Author |
This class implements a genetic algorithm to optimize a population of chromosomes.
It provides a base class that implements several steps of a genetic algorithm like initializing the population, selection, fitness function, cross-over, mutation and get the best sequence.
The class can be extended by specialized sub-classes that override the population initialization or other steps to customize the genetic algorithm to solve specific optimization problems. | |

Example
<?php
/*
this example show how we use SimpleGeneticAlgorithm
*/
require __DIR__ . '/../vendor/autoload.php'; // composer autoload
$ga = new \SimpleGeneticAlgorithm\SimpleGeneticAlgorithm(array(
//'population' => 20,
//'selection' => 90, // 90%
'mutation' => 25, // 25%
//'seed' => 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ 1234567890\'.,',
'goal' => 'Astari Ghaniarti',
//'max_iteration' => 50000,
'delay' => 50, // ms, if debug is false, then delay forced to 0
'debug' => true,
//'fitness_in_percent' => false, // usefull if chromosome more than 10 chars
));
//var_dump($ga->run());
$ga->run(); // just run because debug is true

Details
SimpleGeneticAlgorithm
simple genetic algorithm in php,
this package i create just for example how we can implement Genetic Algorithm in PHP
if you inteserted just email me at [email protected] :-)
see interface/GeneticAlgorithm.php
Installation
you can download this with composer (packagist)
<pre><code>composer require ryanhs/simple-genetic-algorithm</code></pre>
Example
in example dir you can see:
-
example1.php
-
example2.php
-
example3.php
example 1
<pre><code>
require '/vendor/autoload.php'; // composer autoload
$ga = new \SimpleGeneticAlgorithm\SimpleGeneticAlgorithm(array(
'mutation' => 25, // 25%
'goal' => 'Astari Ghaniarti',
'delay' => 50, // ms, if debug is false, then delay forced to 0
'debug' => true,
));
$ga->run(); // just run because debug is true
</code></pre>
