Fuzzy logic does not have to be hard to understand, even though the math behind it can be intimidating, especially to those of us who have not been in a math class for many years. Binary logic is either 1 or 0. Fuzzy logic is a continuum of values between 0 and 1. This may also be thought of as 0% to 100%.

What is Fuzzy Logic?

As per the Boolean Logic, value 1 refers to True, and 0 means False. The term Fuzzy refers to something unclear or vague. The computer cannot easily understand such cases. Thus, it cannot produce an exact result of True or False. But a Fuzzy Logic algorithm makes systems more intelligent and helps them understand the problems where there may be other answers than true or false.
