Fuzzy logic is a form of multi-valued logic derived from fuzzy set theory to deal with reasoning that is approximate rather than precise. Just as in fuzzy set theory the set membership values can range (inclusively) between 0 and 1, in fuzzy logic the degree of truth of a statement can range between 0 and 1 and is not constrained to the two truth values {true, false} as in classic predicate logic. And when linguistic variables are used, these degrees may be managed by specific functions, as discussed below.Some Current areas of application include:Automobile and other vehicle subsystems, such as automatic transmissions, ABS and cruise control (e.g. Tokyo monorail) Air conditioners The Massive engine used in the Lord of the Rings films, which helped huge scale armies create random, yet orderly movements Cameras Digital image processing, such as edge detection Rice cookers Dishwashers Elevators Washing machines and other home appliances Video game artificial intelligence Language filters on message boards and chat rooms for filtering out offensive text Pattern recognition in Remote Sensing This book brings together the latest research in the field.
