FUZZY LOGIC

WHAT IS FUZZY LOGIC?
In classical set theory members of a given set either have full membership in that set or no membership at all, i.e. the "degree of membership" is restricted to either TRUE or FALSE or 1 and 0. Linguistic variables (central to fuzzy logic manipulations) hold values that are uniformly distributed between 0 and 1, and are dependent on the linguistic term.
Applications may be computed in either the fuzzy linguistic domain or the conventional crisp domain. Linguistic variables are relevant in applications involving human interface as tasks commonly done by humans cannot easily be described in crisp terms. Fuzzy logic derives its importance from the fact that most modes of human reasoning and especially common sense reasoning are approximate in nature-they do not have any definite answers and are dependent on many varied factors.
In such cases linguistic variables provide a convenient tool to describe a problem.
