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:

...
Weight summatory:
1* 12 + 0 * 1 + 3 * 4 + 0 * 1 + 2 * 2 = 28

Value summatory:
1* 4 + 0 * 2 + 3 * 10 + 0 * 1 + 2 * 2 = 38

Weight summatory:
1* 12 + 2 * 1 + 0 * 4 + 1 * 1 + 0 * 2 = 15

Value summatory:
1* 4 + 2 * 2 + 0 * 10 + 1 * 1 + 0 * 2 = 9

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.
