What is fuzzy logic and how it works?

What is fuzzy logic?

Fuzzy logic is a variable processing approach that allows multiple truth values to be processed by the same variable.

Fuzzy logic attempts to solve problems by using an open, imprecise spectrum of data and heuristics to generate a range of accurate conclusions.

How  does fuzzy logic work?
Fuzzy logic is intended to solve problems by taking into account all available information and making the best decision possible given the input.

Fuzzy logic is based on the idea of deciding on an output based on assumptions. It operates on the basis of sets. Each set represents some linguistic variables that define the output’s possible state.

 

Each possible state of the input, as well as the degrees of change in the state, is included in the set, from which the output is predicted. It operates on the If-else-the principle, i.e. If A AND B Then Z.
