WebThe 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 make the circuit output "true" are in 1-to-1 … WebWe discuss a transformation of formulas that obtains CNF with only linear blowup in size. However, there is a cost of saving the space.

The expression can be expressed as CNF with just two clauses: $$(\lnot p \lor \lnot r \lor … WebThe Tseitin transformation converts any arbitrary circuit to one in CNF in polynomial time/space. It does so at the cost of introducing new variables (one for each logical connective in the formula). """ from nnf import NNF, Var, And, Or, Internal from nnf.util import memoize.

WebClearly, the CNF resulting from applying the Plaisted-Greenbaum transformation is smaller than the formula resulting from the Tseitin transformation. However, in contrast to the Tseitin transformation, the PG transformation does not preserve the number of satisfying assignments of the original formula (c.f. Model Counting). WebTseitin transformation. Propositional Logic A propositional variable is a Boolean or binary variable, for example, Pand Q. With lowercase letters we indi-cate the truth value assigned to a variable, P = true is written as pand P= false as :p. An interpretation is a truth-value assignment to all variables. A proposi-

In many cases the optimized converters like the Tseitin transformation would give a much smaller output much faster. The parse tree prints a formula as a nested list built by the simple recursive descent parser.
