This is a very rough, and my first ever implementation of a learning neural network using the NEAT algorithm.

It's all in PHP.

It makes use of two non-traditional PHP library. Raylib for graphics and FANN for Neural networks.

https://libfann.github.io/fann/docs/files/fann-h.html#FANN_Creation/Execution

As a drupal web developer, I've fallen on using familar tools and so this all works in lando https://docs.lando.dev/basics/

There is a dockerfile that builds the raylib and fann libraries.

This has only been tested on Ubuntu 21.04

Install lando as per lando docs. clone this repo and cd to it's directly. Run `lando start'.

Just run

lando php neural.php

This looks like an excellect project. The info in the readme, the youtube videos etc have great information.

This library needs to be compiled and linked into PHP, I was unable to get this library to compile and link correctly and fell back to using raylib-ffi which is slower but achieved my demo purposes for now.

This is the library I used to communicate with raylib c library. It's php based library so is installed with composer. simple, easy, slow.

This PHP library appears to be stalled, but not much more than raylib-php is. I haven't looked into this one much as it appears less stable thatn raylib-php and raylib-ffi worked for me.

An excellent overview of the FANN libary in PHP and how to use it. This is essentially a digestible interpretation of the PHP documentation. https://www.youtube.com/watch?v=5bFxDsoNFzU&t=155s

Learn about matrices. maybe. https://www.youtube.com/watch?v=iC13u7tspyg
