To actually answer the question of this post, "AI" stands for artificial intelligence. Intelligence that is coded into machines.
On RA2, we give robots "AI" for tournaments that are hosted on the website because we have found them to be much easier to run than use the horrible online systems for RA2 for tournaments due to the lag and errors.
And yes, I know this might be an alt but either way, I asked the exact same question as him all those years ago so it's only fair if he gets a proper response.
