Predicates

A predicate is a function defined with set of variables, which returns the result True or False. The output of a predicate is a Boolean value as a response when given a set of parameters:

Question

Answer all 3 parts

Consider the following formula in propositional logic. The knowledge base from (1) to (10) is given.
1. (~A => R)n(S => H)
2. A => (B U CUD)
3. E => (B UCUG)
4. (B UC UD) => A
5. (B UC UG) => E
6. Q => (G UCUHUP)
7. Q
8. -F
9. -A
10. E
(1). Converting the above to Conjunctive Normal Form.
(2). From the result of (1), prove G by using reference rules as Method 1 of the lecture note. Write the
process of the proof with the corresponding number of rules and facts.
(3) From the result of (1), prove KB = G by contradiction as to show KB A- G is unsatifiable as
Method 2 of the lecture note. Write the process of the proof with the corresponding number of rules and
facts. You should start with - G for this process.
