  fuzzy logic
       
          A superset of Boolean logic dealing with the concept of
          partial truth -- truth values between "completely true" and
          "completely false".  It was introduced by Dr. Lotfi Zadeh of
          UCB in the 1960's as a means to model the uncertainty of
          natural language.
       
          Any specific theory may be generalised from a discrete (or
          "crisp") form to a continuous (fuzzy) form, e.g. "fuzzy
          calculus", "fuzzy differential equations" etc.  Fuzzy logic
          replaces Boolean truth values with degrees of truth which are
          very similar to probabilities except that they need not sum to
          one.  Instead of an assertion pred(X), meaning that X
          definitely has the property associated with predicate
          "pred", we have a truth function truth(pred(X)) which gives
          the degree of truth that X has that property.  We can combine
          such values using the standard definitions of fuzzy logic:
       
          	truth(not x)   = 1.0 - truth(x)
          	truth(x and y) = minimum (truth(x), truth(y))
          	truth(x or y)  = maximum (truth(x), truth(y))
       
          (There are other possible definitions for "and" and "or",
          e.g. using sum and product).  If truth values are restricted to
          0 and 1 then these functions behave just like their Boolean
          counterparts.  This is known as the "extension principle".
       
          Just as a Boolean predicate asserts that its argument
          definitely belongs to some subset of all objects, a fuzzy
          predicate gives the degree of truth with which its argument
          belongs to a fuzzy subset.
