Tseitin transformation example
WebNov 10, 2024 · The Tseitin transformation converts an arbitrary logic formula to conjunctive normal form. The approach is to i) associate new variables with sub-parts of the formula using logical equivalence relations, (ii) to restate the formula by logically $\text{AND}$ -ing these new variables together, and finally (iii) manipulate each of the equivalence relations … Webapproaches for transforming Horn clauses. Section 4.1 recounts a query-answer transformation used by Gallagher and Ka e in recent work [30,46]. In Section 4.2 we recall the well-known fold-unfold transformation and use this setting to recast K-induction [64] in the form of a Horn clause transformation. Section 4.3 dis-

The Tseytin transformation, alternatively written Tseitin transformation, takes as input an arbitrary combinatorial logic circuit and produces a boolean formula in conjunctive normal form (CNF), which can be solved by a CNF-SAT solver. The length of the formula is linear in the size of the circuit. Input vectors that … See more The naive approach is to write the circuit as a Boolean expression, and use De Morgan's law and the distributive property to convert it to CNF.
