Alan Turing, one of the greatest mathematicians and computer scientists in British history. Some of his scientific achievements in science, especially in mathematical logic and computer science, formed the basis of modern computer technology. One of Turing's greatest achievements was the introduction of the Turing machine Turing's machine is a mathematical model of an automaton. To eliminate uncertainty, Turing comprehensively analyzed the human computational process, incorporated computer thinking, and reduced computation to the simplest, most basic, and most deterministic operational actions, thus describing in a simple way the kind of basic computational procedures that are intuitively mechanical. This not only gave a completely definitive definition of computation, but for the first time linked it to automata, which had a tremendous impact on later generations. At the same time, Turing also introduced the concept of a general-purpose Turing machine, which is equivalent to an explanatory program for a general-purpose computer, a point that directly contributed to the design and development of later general-purpose computers. At the same time, he also made significant contributions to the Second World War. In order to decipher German telegraph messages, Turing designed an electronic computer for German telegraphs, which performed counting, binary arithmetic and Boolean algebraic logic operations, and used them to complete the code-breaking work brilliantly. In addition, he also made significant contributions to artificial intelligence. In 1950, he published his paper "Computers and Intelligence", which provided the seminal idea for the later science of artificial intelligence. Turing's idea of machine intelligence is undoubtedly one of the direct origins of artificial intelligence. And as the field of artificial intelligence has been studied in depth, the profundity of Turing's ideas has been increasingly recognized: they remain one of the main ideas of artificial intelligence today. Turing is not only famous for deciphering codes, but he also made important contributions in the fields of artificial intelligence and computers, and he is often considered the founder of modern computer science. In honor of his great contributions to computer science, the annual Turing Award was established by the Association for Computing Machinery (ACM) in 1966 to recognize outstanding contributions to computer science.
