DNF

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

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