That's interesting how fast was it botted again. This bot enumerates only about 1000-2000 levels to find a good one.
Wow. Since my desktop computer is broken, my laptop is the only thing I can mine with and it takes me 2.5 seconds just to generate 1 map
AFAIK only 25% of all maps are valid so you also enumerate several maps. There is also some time spend in precomputing some information that is necessary for rendering and bots don't need it.
EDIT: so if we count only valid maps then this bot enumerates only several hundreds.
