The following is a context-free grammar for DNF: DNF → ( Conjunction) ∨ {\displaystyle \vee } DNF DNF → ( Conjunction) Conjunction → Literal ∧ {\displaystyle \wedge } Conjunction Conjunction → Literal Literal → ¬ {\displaystyle \neg } Variable Literal → Variable See more In boolean logic, a disjunctive normal form (DNF) is a canonical normal form of a logical formula consisting of a disjunction of conjunctions; it can also be described as an OR of ANDs, a sum of products, or (in See more Converting a formula to DNF involves using logical equivalences, such as double negation elimination, De Morgan's laws, and the distributive law. All logical formulas … See more An important variation used in the study of computational complexity is k-DNF. A formula is in k-DNF if it is in DNF and each conjunction contains at most k literals. See more • "Disjunctive normal form", Encyclopedia of Mathematics, EMS Press, 2001 [1994] See more The Boolean satisfiability problem on conjunctive normal form formulas is NP-hard; by the duality principle, so is the falsifiability problem on DNF formulas. Therefore, it is co-NP-hard to decide if a DNF formula is a tautology. Conversely, a DNF … See more • Algebraic normal form – an XOR of AND clauses • Blake canonical form – DNF including all prime implicants • Propositional logic See more WebDefinition: A Boolean Algebra is a math construct (B,+, . , ‘, 0,1) where B is a non-empty set, ... • But h(x,y,z)=xy+x’y’z is not in DNF because xy is not a minterm of size 3.
