Man vs. computer: a gaming history
Will Watson win against its human competitors on 'Jeopardy!'?
In 1997, a computer named Deep Blue took a historic victory lap after checkmating world chess champion Garry Kasparov. The IBM computer, capable of processing 100 million board positions a second, was an instant superstar. The win made it less crazy to ask a tantalizing question: Could computers think on their own, and if so, what kind of actions were they capable of?
The word "think" is tricky. Next week, the computer known as Watson will try to beat two "Jeopardy!" champions. Watson is a whiz at math but not at language, so if it wins, a new kind of man vs. machine history will be made. It will show that a computer can dominate at a game that requires reasoning as well encyclopedic knowledge. You can watch Watson in action here.
Years before Kasparov was defeated, in June 1979, computer programmer and chess player Hans J. Berliner's backgammon-playing program beat world champion Luigi Villa 7-1. It is believed to be the first victory by a computer at a game based on strategy, chance and multiple optional positions. Berliner reportedly said that his program wasn't built to analyze millions of moves, like Deep Blue would later, but it computed the benefits and risks of moves.
One of the lesser-known computer victories occurred in the mid-1990s. Marion Tinsley, a math professor and Baptist minister, was the global checkers champ from 1955 to 1992. He lost only seven games in his 45-year career, one of them to a computer in 1994. Called Chinook, the computer was designed by four scientists who worked more than a decade trying to build the perfect checkers dominating program. Tinsley played the machine several times, beat it and then lost in a follow-up match. Chinook went on to beat other humans at the game.
Naturally, the board game of all board games - Scrabble - was next. Don't let its name fool you; Quackle was a formidable Scrabbleist. David Boys, the game's world champion, found that out when the computer beat him in a match in Canada in 2007. But it wasn't like Quackle just walked up to Boys and said, "Let's go." Quackle earned the right to challenge the human only after it defeated another Scrabble program named Maven. Boys was a bit of a sore loser, reportedly telling people that losing to a machine is still better than being a machine.
The same year Quackle won, the first poker game between people and machines involving money was played. A computer project called Polaris, invented at the University of Alberta, beat poker greats Ali Eslami and Phil "The Unabomber" Laak. To be fair, the first time the players faced off against the computer, there was a draw. The computer beat them in the second match. Laak and Eslami brought their A games and won the next two matches.
Ever heard of the game Go? Last summer, a computer beat a Romanian player. The win was remarkable because Go is traditionally challenging for computers. How Stuff Works breaks down why Go is so tough for computers.
But the quest to find out whether man or computer is better at something goes beyond gaming. Computers have been asked to be coaches, design partners, teammates and friends capable of holding conversations with people. In the early 1990s, studies examined computers as social actors, finding that people applied social rules like they were dealing with a person capable of frailties, according to a Stanford University paper summarizing the studies. People even assigned gender to computers based on the sound of the voices coming from the machines, it said.
According to one study, "Individuals can be induced to behave as if computers warranted human treatment, even though users know that the machines do not actually warrant this treatment."
Perhaps that's easier on the ego than knowing a bunch of microchips beat you at the game you play best.
