WebBefore a combinatorial problem can be solved by current SAT methods, it must usually be encoded in conjunctive normal form, which facilitates algorithm implementation and allows a common file format for problems. Webthe main algorithm and investigate its performance in Section 3. Section 4 contains the constructions and proofs related to width automatizability of Tseitin tautologies whereas Section 5 is de-voted to the proofs of our smoothness results. Finally, the paper is concluded in Section 6 with a few open problems. 2. Preliminaries and Results

Webof 2-fold Tseitin formulas. 1 Introduction Splitting is the one of the most frequent methods for exact algorithms for NP-hard prob-lems. It considers several cases and recursively executes on each of that cases. For the CNF satis ability problem the classical splitting algorithms are so called DPLL algo- 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 … 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. However, this can result in an exponential increase in equation size. The … See more The output equation is the constant 1 set equal to an expression. This expression is a conjunction of sub-expressions, where the satisfaction of each sub-expression enforces the proper … See more Presented is one possible derivation of the CNF sub-expression for some chosen gates: OR Gate An OR gate with two inputs A and B and one output C is satisfies the following conditions: See more The following circuit returns true when at least some of its inputs are true, but not more than two at a time.

"WebLogic circuits can be encoded in CNF e ciently using Tseitin transformation. Such a conversion usually causes information loss. The logic paths and gates are lost. Therefore, algorithms have been proposed that aim at reconstructing circuit structures from CNF. Using these techniques might allow to apply circuit-SAT techniques to arbitrary CNFs.
