Fuzzy Logic

Concept of Fuzzy Logic described with an illustration

Fuzzy Logic is an often discussed topic in fields of Expert Systems and Logic Programming.

It refers to the logic which is not of the binary form, i.e. 0 or 1. The value of this logic lies somewhere between true and false. So, we can say that fuzzy logic is a logic whose output lies partially in 0 and partially in 1, or partially in true and partially in false. The concept of fuzzy logic in Computer Science is similar to the concept of Probability in Mathematics, where the solution lies between 0 and 1 but never has an exact value. So, the value of the fuzzy logic is greater than 0 but lesser than 1. The above picture shows a vehicle partially in the state of a car and partially in the state of a motorcycle. So, you can easily recall the definition of Fuzzy logic by remembering this picture, that the Fuzzy Logic is a logic that has multiple values and never has an exact value.
