One day, i was playing with Nullpo's AIs under different settings and rules, seeing if they can reach high grades or scores on some modes. The results were...varied. But the point is, i don't know some things about Nullpo's AIs: 1 - How they work, what they analyze and what they can do after this... 2 - There's a Game mode, Rule or setting that the AIs play they best? I would like to see individual answers for each AI (Poochybot, RanksAI, Basic...), but if this is asking too much, you don't need to do individual answers, just try to answer the 2 main questions
PoochyBot attempts to get tetrises, and is optimized for playing Grade Mania 3. WIth a little luck and a decent spec computer) it can become GM.
Classic3. It wasn't written to consider other rotation rules, and is likely to horrifically fail if used with anything else.
