The world of artificial intelligence was revolutionized in 1997 when a computer named “Deep Blue” defeated the reigning world chess champion Garry Kasparov in a six-game match. It was a historic moment, as it was the first time a machine had surpassed a human in a complex game like chess. The victory of Deep Blue was not only a milestone in the field of AI, but it also raised questions about the capabilities and limitations of machines and sparked a discussion on the future of human vs. machine competition.

The Development of Deep Blue

The project to create Deep Blue was initiated by IBM in 1985 as a part of their Deep Computing research program. It was the brainchild of Carnegie Mellon University computer scientists Feng-hsiung Hsu, Murray Campbell, and Thomas Anantharaman. The purpose of the project was to build a chess-playing computer capable of defeating the best human players in the world. The first iteration of the machine, called “ChipTest,” was created in 1988, and over the next few years, it underwent several improvements in hardware and software. The final version, Deep Blue, was completed in 1997 and was considered one of the most powerful supercomputers of its time.

How Deep Blue worked

Deep Blue was a sophisticated machine, and its computational abilities were far beyond that of a human mind. It was designed to evaluate more than 200 million positions per second and make decisions based on its evaluation. The machine used two layers of parallel processors, with 480 special-purpose VLSI chess chips, each capable of evaluating 8 million positions per second. It also utilized a 512-node massively parallel RS/6000 computer architecture that used a massively parallel search algorithm developed by IBM researchers. This combination of hardware and software enabled Deep Blue to search the game tree up to eight moves ahead and make decisions based on the best possible move.

The Match Against Garry Kasparov

The highly anticipated match between Deep Blue and Garry Kasparov took place in May 1997 in New York City. The six-game match was full of dramatic moments and intense competition. Deep Blue won the first game, which was the first time a computer had defeated a world champion in a regulation (non-blitz) game. Kasparov managed to win the second game, and the next three games ended in a draw. Going into the final game, the score was tied at 2.5-2.5. In the sixth game, both Kasparov and Deep Blue made mistakes, but it was Deep Blue´s blunder in the opening that proved fatal for the computer. Kasparov won the final game, and the final score was 4-2 in his favor.

Deep Blue´s victory over the world champion was hailed as a significant achievement for AI, but it also sparked controversy. Kasparov accused IBM of cheating and demanded a rematch. IBM refused, stating that they were dismantling Deep Blue to use its parts in other projects. However, a rematch took place in 1997, where Kasparov was the victor, winning three games and drawing two. The final score was 3.5-2.5 in Kasparov´s favor.

The Legacy of Deep Blue

The victory of Deep Blue over Garry Kasparov brought AI and supercomputing into the mainstream media. It proved that machines were capable of defeating humans in complex games, opening the door for further exploration and research in the field of AI. After its victory, Deep Blue was retired, but its legacy lived on. The technology used in Deep Blue paved the way for significant advancements in AI, including the development of IBM´s Watson, which won the game show “Jeopardy!” in 2011. The match between Deep Blue and Kasparov is still considered a significant moment in the history of AI and is studied and analyzed by researchers and enthusiasts alike to this day.

In conclusion, Deep Blue´s victory over Garry Kasparov was a groundbreaking moment in the history of AI. It showed that machines had the potential to outperform humans in complex tasks and sparked a conversation about the future of AI and human-machine competition. Deep Blue´s legacy continues to inspire and drive advancements in the field of AI, making it a crucial milestone in the development of artificial intelligence.
