WebSep 13, 2024 · Suppose I have the following logical expression: (A ∧ ¬C) ∨ (B ∧ C) ∨ (A ∧ B) Why does this simplify to (A ∧ ¬C) ∨ (B ∧ C)? The truth tables are the same but I cannot get to the second expression with my current knowledge of the laws. WebKB = (B 1,1 ⇔ (P 1,2 ∨ P 2,1)) ∧¬ B 1,1 in CNF… (¬B 1,1 ∨ P 1,2 ∨ P 2,1) ∧ (¬P 1,2 ∨ B 1,1) ∧ (¬P 2,1 ∨ B 1,1) α = ¬P 1,2 Resolution yielded the empty clause. The empty clause is False (a disjunction is True only if at least one of its disjuncts is true). 18

WebA ∧ B ∧ ¬ C and (A ∨ ¬ B) ∧ (A ∨ C) are two examples of statements in CNF. Also, here the normalised statements are fully converted to CNF, meaning that all redundancies are eliminated.
