Artificial intelligence (AI). It is a new technical science to study and develop theories, methods, technologies and application systems that simulate, extend and expand human intelligence. Artificial intelligence is a branch of computer science, which tries to understand the nature of intelligence and produce a new intelligent machine that can respond in a way similar to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system. The term "artificial intelligence" was first put forward at the Dartmouth Society in 1956. Since then, researchers have developed many theories and principles, and the concept of artificial intelligence has also expanded. Artificial intelligence is a challenging science, and people engaged in this work must understand computer knowledge, psychology and philosophy. Artificial intelligence is a very extensive science, which is composed of different fields, such as machine learning and computer vision. Generally speaking, one of the main goals of artificial intelligence research is to enable machines to be competent for some complex tasks that usually require human intelligence. But in different times, different people have different understandings of this "complex work". For example, heavy scientific and engineering calculations were originally undertaken by the human brain. Now the computer can not only complete this calculation, but also do it faster and more accurately than the human brain. Therefore, contemporary people no longer regard this kind of calculation as "a complex task that needs human wisdom to complete". It can be seen that the definition of complex work changes with the development of the times and the progress of technology, and the specific goals of artificial intelligence naturally develop with the changes of the times. On the one hand, we have made continuous progress, on the other hand, we have turned to more meaningful and difficult goals. At present, the main material means that can be used to study artificial intelligence and the machine that can realize artificial intelligence technology are computers. The development history of artificial intelligence is related to the development history of computer science and technology. In addition to computer science, artificial intelligence also involves information theory, cybernetics, automation, bionics, biology, psychology, mathematical logic, linguistics, medicine, philosophy and many other disciplines. The main contents of artificial intelligence research include: knowledge representation, automatic reasoning and search methods, machine learning and knowledge acquisition, knowledge processing system, natural language understanding, computer vision, intelligent robots, automatic programming and so on.

A computer or software program (usually abbreviated as a program) refers to a set of instructions that indicate each step of a computer or other equipment with information processing capabilities. It is usually written in a programming language and runs on a specific target architecture. For example, a program is like a braised pork recipe (program) written in Chinese (programming language), which is used to guide people who know Chinese and cooking technology (architecture) to cook this dish. Usually, computer programs should be compiled and linked into a format that is not easy to be seen by people and can be read by computers, and then run. Programs that can be run without compilation are usually called scripts.
