fuzzy logic
     n : a form of mathematical logic in which truth can assume a
         continuum of values between 0 and 1

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 predx, meaning that x
        definitely has the property associated with predicate
        "pred", we have a truth function truthpredx which gives
        the degree of truth that x has that property.  we can combine
        such values using the standard definitions of fuzzy logic:
     
        	truthnot x   = 1.0 - truthx
        	truthx and y = minimum truthx, truthy
        	truthx or y  = maximum truthx, truthy
     
        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.
