Baby Steps First 👶

This was my first attempt at reinforcement learning, before chomping off a huge bite, lets train a simple bot. Yes, I studied Q Learning and Q tables, and jumped right into Deep Reinforcement Learning.:laughing:

This is a POC of sample code from the tf_agents documentation and my idea for a good challenge similar to Halite::thinking:

Goal: The white dot to find the green dot
Avoid: Falling off the map or taking too many steps

• On a 5x5 Grid and a typical 2018-2020 CPU/GPU, training time can take ~4k steps and 10-15 minutes. w/ >95% Win rate.
• On a 6x6 Grid and a typical 2018-2020 CPU/GPU, training time can take ~12k steps and 40-60 minutes w/ >95% Win rate.
• ...
• On a 15x15 Grid and a typical 2018-2020 CPU/GPU, training time can take ~10M-20M steps and 1-2 days w/ >95% Win rate.:woozy_face:
  • Can anyone help improve this?
