Artificial intelligence: Definition, Different methods and Applications.

General Definition: Artificial intelligence is a branch of computer science, which is concerned about the study of mechanisms of intelligent human behavior. It is done by simulation using artificial artefacts, usually with computer programs on a calculator (computer simulation). Realistic definition: The general meaning of AI suffers from the fact that the terms "intelligence" and "intelligent human behavior" themselves are not yet well defined and understood. On the other hand, AI is also a tool that can be used to empirically test theories of intelligence. The execution of programs on computers represents empirical experiments.
