 Fuzzy logic emerged in the context of the theory of fuzzy sets, introduced by Lotfi Zadeh (1965). A fuzzy set assigns a degree of membership, typically a real number from the interval \([0,1]\), to elements of a universe. Fuzzy logic arises by assigning degrees of truth to propositions. The standard set of truth-values (degrees) is the real unit interval \([0,1]\), where \(0\) represents “totally false”, \(1\) represents “totally true”, and the other values refer to partial truth, i.e., intermediate degrees of  truth.[1]
