The function as-cnf first removes any implication, distributes (not wff) applying De Morgan's laws, removes double negations and finally distributes ORs over ANDs.

This C++ code is designed to analyze and process logical (propositional) formulas, with the ultimate goal of generating a truth table and constructing the Conjunctive Normal Form (CNF) and Disjunctive ...

Abstract: In this paper, we put forward a weak conjunctive normal form for G3, which is similar to the conjunctive normal form for classical propositional logic. We also give two algorithms to reduce ...

Abstract: In this paper, we introduce an automated conversion-verification methodology to convert a Directed Formula (DF) into a Conjunctive Normal Form (CNF) formula that can be fed to a SAT solver.

Describe the definition of (Boolean) Satisfiability Problem (SAT). Describe conjunctive normal form (CNF). Understand the algorithm DPLL for solving SAT problems. Describe and create a Successor-State ...
