On this day, 28 years ago, on May 11, 1997 (April 5, 1997 in the lunar calendar), world chess champion Kasparov played against the supercomputer Deep Blue. Kasparov is playing against the super computer "Deep Blue"(the live operator of "Deep Blue" on the right) On May 11, 1997, the six-game match between world champion Kasparov and IBM's chess computer "Deep Blue" came to an end. After the first five games were tied 2.5 to 2.5, Kasparov surrendered to Deep Blue after only 19 steps in the sixth set decider. The entire game lasted less than an hour. Deep Blue won this confrontation of special significance. This result was already visible at the end of the second game. Deep Blue's flawless victory in the game was a serious blow to Kasparov's confidence. After the game, his assistant saw him sitting in the corner of the room, his hands covering his face. The subsequent three draws in the third, fourth and fifth games exhausted Kasparov's fighting spirit and his physical strength. According to reports, Kasparov said after the game that in the last game,"I was no longer able to fight again." No one has ever troubled Kasparov so much. Since becoming a world champion in 1985, his position in the field of chess has not been severely challenged in the past 12 years. In the newly released ranking, he ranks first, with a ranking score of more than 2800 points. No one has ever reached this level. He is considered one of the strongest chess players of all time. In the first five games, he had always adopted a specially designed strategy to deal with "Deep Blue". In order to avoid direct wrestling with "Deep Blue" with powerful computing power, he chose a weird start and tried to avoid contact with chess pieces. This method surprised all the experts. However, this did not achieve significant results. No matter what move the opponent uses, Deep Blue always silently and quickly moves out of the strongest hand. In the last game, Kasparov obviously lost patience and adopted a "normal" approach for the first time. The first few moves cheered the watching chess fans, thinking that the powerful Kasparov had regained his true colors. But joy quickly turned into depression. In the seventh round, Kasparov made an irreparable low-level mistake, and the situation took a sharp turn. Soon Kasparov was hopeless. After struggling for a few steps, he gave up resistance and hastily signed the alliance under the city. This is another new record set by "Deep Blue". In 1988, its predecessor Deep Thought was the first computer to win a chess grandmaster; in 1996, Deep Blue became the first computer to win a chess world championship; now, it has become the first computer to defeat a chess world championship in multiple games. Kasparov once said that if a computer wants to defeat the world championship, it will have to wait until 2010, and Deep Blue has advanced this date by 13 years. "Deep Blue" weighs 1.4 tons and has 32 nodes. Each node has 8 processors specially designed for chess games. The average computing speed is 2 million steps per second. A total of 256 processors are integrated into the RS6000/SP parallel computing system developed by IBM, resulting in an astonishing speed of more than 200 million steps per second. It will not be tired, will not have psychological ups and downs, and will not be disturbed by opponents. Its flaw is that it has no intuition and cannot really think. But the competition process showed that Deep Blue's endless computing power largely made up for these shortcomings, which in turn made people think, what is the nature of thinking? Is thinking mysterious? To what extent does Deep Blue's confrontation with Kasparov enlighten this question? The IBM development team input Deep Blue's opening and endgame methods for all international grandmasters over the past 100 years. Since losing to Kasparov 2:4 in 6 games in 1996, Deep Blue's computing speed has doubled. American grandmaster Benjamin joined the "Deep Blue" team and programmed his understanding of chess to "Deep Blue". After the game ended, the "Deep Blue" team announced a secret. After each game ended, the team would modify specific parameters accordingly according to Kasparov's situation. Although "Deep Blue" could not think, these tasks actually played a role in forcing it to learn, which was the main reason why Kasparov was never able to find an effective way to deal with "Deep Blue". Today's "Deep Blue" is no longer the "Deep Blue" of 1996. This victory of "Deep Blue" marks a new level in computer technology. We will have to seriously think about the relationship between people and computers. It is said that Kasparov could not sleep all night after losing the second game. At this time, not just Kasparov, but all of us must learn to accept the reality that computers are enough to compete with humans in some ways.
