What amazes me at the end of the day is that brute-forcing seem to do much better than I initially thought it would do.

Trying random stuff just sounds stupid but with enough compute and data, I guess it could overpower smart creatures like us.

I agree that CodeCraft is vastly simpler than StarCraft but the idea is the same. just try random stuff(sometimes with better logic behind it) until something works and then optimize it to perfection.
