IBM's Deep Blue was a pioneering chess-playing computer developed by IBM in the late 20th century. It gained fame for its ability to compete against and defeat human chess champions, most notably Garry Kasparov in 1997. Deep Blue utilized advanced algorithms and massive processing power to evaluate millions of possible moves per second. The project aimed to explore artificial intelligence and its applications in complex problem-solving. Deep Blue's victory marked a significant milestone in the field of AI, demonstrating the potential of computers to perform tasks traditionally reserved for human intelligence, particularly in strategic games like chess.
