CNF

A propositional formula is a CNF formula, meaning Conjunctive Normal Form, if it is a conjunction of disjunction of literals (a literal is a propositional variable or its negation). Hence, a CNF is a formula of the form: $K_{1}\\wedge K_{2}\\wedge\\ldots\\wedge K_{n}$ , where each $K_{i}$ is of the form $l_{i1}\\vee l_{i2}\\vee\\ldots\\vee l_{im}$ for literals $l_{ij}$ and some $m$ (which can vary for each $K_{i}$ ).

Example: $(x\\vee y\\vee\eg z)\\wedge(y\\vee\eg w\\vee\eg u)\\wedge(x\\vee v)$ .
