This page gives an overview of what computational intelligence actually is and what we do with it. A general definition could be that CI is the study and design of intelligent agents , where an agent can be anything that reacts to its environment.
Intelligent agents react in an intelligent manner.
They are able to adapt to their environment, show learning behaviour and make decisions based on information they retrieve and remember. People are prime examples of intelligent agents. However, though people can be studied, they cannot be designed. It can be subdivided into such concepts as Genetic Algorithms, Genetic Programming, Evolutionary Strategies and Artificial Life. The term fuzzy relates to the type of data it processes, not to the technique itself, which is very exact.
