It's already being done. Has been done for decades now. Definitely wouldn't be a good use of an LLM-type model if that's what you're proposing
If you look at the placement of Journal of Cellular Automata in SciMago's Shape of Science visualization[0] you'll see that it's completely surrounded by machine learning/AI journals
The Game of Life is Turing complete. And therefore a complete analysis of how to write programs in it would imply a solution to the Halting problem. Which is impossible.
“Easily verifiable”… Not really, you have to simulate 133_076_755_768 steps. Sure it’s doable. But if the AI suggests a thousands patterns, then it will be useless.
