Lofti Zadeh, Father of Fuzzy Logic (1965).
Fuzzy Logic is determined as a set of mathematical principles for knowledge representation based on degrees of membership rather than on crisp membership of classical binary logic.

Fuzzy Logic
Fuzzy Logic is multi-valued compared with the Boolean Logic which accepts only two values.

Membership Function
(1) Triangular
(2) Trapezoidal
(3) Singleton
(4) Sigmoid
(5) Gaussian

A Fuzzy System can be divided in
(1) Fuzzyfication
(2) Fuzzy Rules
(3) Inference Engine
(4) Defuzzyfication
