You are washing clothes by hand and find that some clothes are unusually dirty. You then use more water and add more detergent. As humans, we can adapt easily to that situation. Why?

1. Now, imagine there are two washing machines. One of them (A) is equipped with fuzzy logic. The other one (B) is not. Which one can adapt to unusually dirty clothes? And how exactly a washing machine can adapt to such situation?
2. Can washing machines face constantly changing condition? Please use some examples to support your answer.
3. Write a pseudocode for a washing machine that equipped with fuzzy logic, when the start washing button is pressed. Assume that a user may wash more than washer capacity and that some of the clothes are very dirty. The machine may learn from last washing session.
