To show the importance of fuzzy logic, we will begin this tutorial by introducing two approaches to solve a decision problem: the classical approach and the fuzzy approach, with the help of an easy example obtained fromMatlab's tutorial.

Let's consider the Tipping Problem:

Given a number between 0 and 10 that represents the quality of service at a restaurant, what should the tip be?

Next: Classical approach
