Artificial intelligence technology, born in the 1950s, is a comprehensive technical science that researches and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. The development of artificial intelligence technology has experienced several ups and downs, as new breakthroughs are constantly achieved in the spiral process upwards. The human-machine game is an important branch of artificial intelligence. In the past 20 years, there have been numerous “human-machine battles” that can be regarded as milestones. This book starts from several milestones of human-machine games, and gives a detailed introduction to the important figures, nodes and technology breakthroughs in the process of technology development. Then it sorts out the evolution of the research methodology of artificial intelligence and proposes a prospect for the future development direction of artificial intelligence technology.
