SnakeAI

Feed Forward Neural Networks evolving to play Snake

• Code for the Neural Networks and Genetic Algorithms is neuroga.
• snake.py - internal model of snake game (independent of graphics, etc)
• engine.py - graphical front-end. Used to actually play snake game (or show a Neural Network playing the game in real time)
• trainer.py - run this script to run the Genetic Algorithm to train Neural Networks (will be saved in model/ directory).
  • NB: trainer will interact with internal snake game model directly for performance reasons so there is no real-time graphics as it trains
  • will show graphs of progress, though (fitness-time and rate of fitness-time graphs)
• notes.txt - small notes I took for myself while developing this project

Usage

You need to have Python 3 installed

Install numpy and pygame
