Here is a fun little diversion to waste some of your time. Check out Akinator, the Web Genius. It is an online “guess what you are thinking of” game like those little electronic 20Q games. This one guesses characters, real or otherwise – anything from celebrities to cartoon characters. It works surprisingly well, starting with broad questions, then throwing in some odd details, then – hey wait a minute is it getting close? then Wow! He got it! These must use an interesting algorythm that seems to be more advanced than a straight decision tree. The questions do not start the same every time, and it will frequently surprise you with the correct answer after seemingly not asking anything very specific to your answer. This one in particular is interesting in that it has more options than just yes or no. You can also answer ‘probably”, “probably not” or “I don’t know”.
