Multivalued logic or many-valued logic differs from classical logic by the fundamental fact that it allows for partial truth. In classical logic, truth takes on values in the set {0, 1}—in other words, only the value 1 or 0, meaning “Yes, it's true,” or “No, it's not,” respectively. Multivalued logics as their natural extension take on values in the interval [0, 1] (any value between and including 0 and 1) or even [0, ∞] (any value from 0 and up to but not including infinity). These logics are also sometimes called intuitionistic logics, and they have become a special subfield in mathematical logics. Multivalued logic is an appropriate logical calculus to use to address uncertainty and imprecision and is a suitable model for examining ...
