## 22 Artificial Intelligence Fuzzy Logic Questions and Answers:

### 1 :: What is Artificial Intelligence Fuzzy Logic?

Fuzzy logic is a form of many-valued logic; it deals with reasoning that is approximate rather than fixed and exact. In contrast with traditional logic theory, where binary sets have two-valued logic: true or false, fuzzy logic variables may have a truth value that ranges in degree between 0 and 1. Fuzzy logic has been extended to handle the concept of partial truth, where the truth value may range between completely true and completely false. Furthermore, when linguistic variables are used, these degrees may be managed by specific functions.

### 2 :: Where do we implement Artificial Intelligence Fuzzy Logic?

It's a multi valued logic.

In Boolean logic is two valued logic,where we will say

an element belongs to a set with membership 1, if it

doesn't belongs to the set then it's membership is 0.

Where as in fuzzy sets we say degree of membership

between 0 and 1.

For example,we have a set of men age.

In Boolean logic a person X aged 51 we will say x is old

and a person Y aged 49 we will say young.

In fuzzy logic we say X belongs to the old men set with a

membership of 0.51 and to young men set with a membership of

0.49

So Boolean logic is our Black&White TV where as Fuzzy logic

is Color TV Fuzzy logic is a Discrete spectrum of values.

### 3 :: This set of Artificial Intelligence MCQs focuses on "Fuzzy Logic - 1".

1. Fuzzy logic is a form of

a) Two-valued logic

b) Crisp set logic

c) Many-valued logic

d) Binary set logic

c) Many-valued logic

Explanation: With fuzzy logic set membership is defined by certain value. Hence it could have many values to be in the set.
