## fuzzy logic

n
(Logic) a branch of logic designed to allow degrees of imprecision in reasoning and knowledge, typified by terms such as 'very', 'quite possibly', and 'unlikely', to be represented in such a way that the information can be processed by computer

## fuzz′y log′ic

n.
the theory of a mathematical set (fuzz′y set′) having the property that each of its members is described in terms of a number, with a value in the range from 0 to 1, that indicates the degree on a spectrum of values to which the member belongs to the set.
