Fuzzy logic
Fuzzy logic is a form of many-valued logic in which the truth values of variables may be any real number between 0 and 1, considered to be "fuzzy".
By contrast, in Boolean logic, the truth values of variables may only be 0 or 1, often called "crisp" values.
Description
Fuzzy logic has been employed to handle the concept of partial truth, where the truth value may range between completely true and completely false.
Furthermore, when linguistic variables are used, these degrees may be managed by specific (membership) functions.
The term "fuzzy logic" was introduced with the 1965 proposal of fuzzy set theory by Lotfi Zadeh.
Fuzzy logic had however been studied since the 1920s, as infinite-valued logic—notably by Łukasiewicz and Tarski.
Fuzzy logic has been applied to many fields, from control theory to artificial intelligence.
