Lunar lander is a one of the problems in Open AI Gym, where you test AI against standard set of problems: https://www.gymlibrary.dev/environments/box2d/lunar_lander/

Then you have stable baselines which implements popular reinforcement learning algorithms to solve these gym problems: https://stable-baselines3.readthedocs.io/en/master/

Shamless plug: I've built a series of games where you solve puzzles (2048) / toy problems (MDP) like the lunar lander using various AI and ML algorithms.

Looking at your website I’m curious how exactly you’re building «ChatGPT for mobile games»? Are you using language models to build these AI solvers?

Well to be honest it is just a marketing term I am using to try to get some attention.

In a way what I am building is a "general AI engine" that is capable of taking in an arbitrary game and play it, which is somewhat conceptually similar to how ChatGPT is a general AI that is able to solve a wide range of text-based tasks.

Yes, I would like to see the environment ported to Python, wrapped in gym, and given a good shaped reward, i.e. like reward = prior_height_delta - (height - target_height) - fuel_cost. Run Stable Baselines PPO or DQN on that and it should converge to something close to an optimized MPC controller.

It is already there, just not this particular implementation (or maybe it is?).

You can run PPO or DQN right now on the Open AI Gym implementation using Stable-Baselines3: https://stable-baselines3.readthedocs.io/en/master/

In fact I previously ran it locally and PPO solved the problem within 10 minutes of training with max reward of about 200.

This is a different lunar lander than you are maybe thinking. It looks more like SpaceX's Starship than an Apollo lunar module. I don't think it has been made into a gym env yet but that would be great if it is!

I wish I could play them in the browser instead of with apps.

I didn't make it available on web because it would be hard to monetize it (happy to be corrected if I'm wrong on this).

I'm working as an indie game dev full-time so making money is high on priorities.
