Hello my dear coders, Hope you like the video. It was my first reinforcement learning experience. I must say it wasn't easy.
My best score was 66, as in the video. I want you to mention your highest scores in the comments, with alpha and gamma values.
This code may be enhanced by adding more states to the RLSnake function. The snake fails when it gets trapped by itself. So we need to add a state that if the snake is in a trap or not.
Please, like and subscribe!
Enjoy and safe coding :)
