AI Tutorial

Where can I find a good AI tutorial that maybe teaches me about some of the basic AI functions? At the moment I'm just learning from looking at Blizzard's AI files, and everything's going fine so far, but I don't really want to look up each and every function to see what it does ^^. It would only need to be something basic just to get me started(I remember there used to be one up, but I can't get to it), and I can figure the rest out on my own.
