🎬 Coding Quests Episode 1: Implementing the NEAT Algorithm from scrach in C++ 🎬 🔍 What's this video about? I was reading a lot about genetics lately, so I got inspired to write code on that topic. I actually wanted to build a simulation with creatures that are evolving over time because I saw multiple videos on that topic and they looked fun. However, I ended up implementing the NEAT algorithm because I was very curious how it works in detail. I also trained 2D snake AI and I got some surprising results that I'd like to share. For the end, I played a bit with "genetic engineering".
