The second boy says, "That's nothing. My Dad scribbles a few words on a piece of paper, he calls it a song, they give him $100."
Little Johnny says, "I got you both beat. My Dad scribbles a few words on a piece of paper, he calls it a sermon, and it takes eight people to collect all the money!"
Computer chessIn 1996, world chess champion Gary Kasparov defeated Deep Blue, IBM's chess-playing computer, by winning a six-game match 4-2, in a regulation-style match held in Philadelphia, as part of the ACM Computer Science Conference. Deep Blue is an improved version of the older Deep Thought, augmented by parallel special-purpose hardware. Deep Blue uses a selectively deepening search strategy, using improvements of the alpha-beta search strategy, with powerful evaluation functions. Transposition tables help avoid unnecessarily calculating the same position more than once. Two powerful databases further augment Deep Blue's play. Deep Blue would defeat Kasparov - the first time the grandmaster ever lost a six-game match in championship play.
