An approach to designing intelligent systems using mathematical algorithms. It consists of the fields of neural networks, evolutionary computation, and fuzzy sets. The term was first used as an alternative to artificial intelligence in the 1980s. The current popular use of the term as defined above results from an effort by James Bezdek in the early 1990s to differentiate the fields of neural networks, evolutionary computation, and fuzzy sets from classical artificial intelligence (AI). There is significant continuing research in the area of computational intelligence, as well as a number of examples of practical, everyday systems that make use of computational intelligence approaches.
