You can read the white paper if you want: https://deepmind.google/discover/blog/alphaevolve-a-gemini-powered-coding-agent-for-designing-advanced-algorithms/

Actually, AlphaEvole already did it. They discovered new algorithms that improve the computation efficienty of matrix multiplication for the first time for 50 years. And a lot of other things. It’s using a custom version of gemini.
