How Stuff Works: How IBM’s Watson machine works

How Stuff Works: How IBM’s Watson machine works: "The last time a computer famously beat humans, the domain was chess. The thing that was most interesting about that victory is the dichotomy between humans and machines. The way a human plays chess and the way that a chess-playing computer plays chess have nothing in common. The computer uses a brute-force technique that looks at billions of possible moves to pick the best moves. A human can’t do anything close to that, so instead looks at many fewer possibilities through a lens of strategy and tactics. Technology has advanced to the point where it is now possible for a laptop computer to use brute force to beat most normal human players."
