WebA propositional formula is in conjunctive normal form (CNF) if it is the conjunction of disjunctions of literals. As noted above, Y is a CNF formula because it is an AND of OR’s. The literals of Y are A,:B, B,C, and :D; the disjunctions are (A _:B) and (B _C _:D); and Y is the conjunction (AND) of the two disjunctions. 3.1 Converting to DNF burch \\u0026 associates lincoln neWebResolution and CNF •Resolutionis a single rule of inference that can operate efficiently on a special form of sentences. •The special form is called conjunctive normal form(CNF) or clausal form, and has these properties: –Every sentence is a disjunction (OR) of literals (clauses) –All sentences are implicitly conjuncted (ANDed). halloween costume jellyfish umbrellaWeb• This form is called a Conjunctive Normal Form, or CNF. – ∨¬ ∧ ¬ ∧ ∨ is a CNF –(∨¬∨) is a CNF.
