There is a sample of genetic algorithm application as a an automated test. For running it, first run composer update for install the dependencies, and then run:
vendor/bin/phpunit --bootstrap vendor/autoload.php tests/An example of test output:

OK (1 test, 1 assertion)Create a class that implements Fgsl\GeneticAlgorithm\RulesInterface. This class must define fitness function and other constraints.
Inject an instance of rules class in an instance of Fgsl\GeneticAlgorithm\GeneticAlgorithm and call method execute.
