this is a fairly interesting question for you to ask.

i put it to you to think about how you can write a scrabble solver, if you're given the official word list. I don't think it's that much of a step up from a sudoku solver!

Yes, it would, and it does. Or not so much AI as brute force code. You can download a Scrabble cheating app on the iPhone right now.

Scrabble is an easily solved problem... No AI necessary, just brute force.
