WebWe discuss a transformation of formulas that obtains CNF with only linear blowup in size. However, there is a cost of saving the space. WebThe conversion algorithm used is very simple and does not perform any optimizations. 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.

Webk, by going through circuits, and then transform circuits into formulas using Tseitin transformation. 1 Nondeterministic Space is Closed under Complement In this section we prove that st-CONN ∈NL. Recall that for st-CONN, the input instance is a directed graph Gwith two distinct vertices sand tand the instance is a YES instance iﬀ there is 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 make the circuit output "true" are in 1-to-1 correspondence with assignments that satisfy the formula.
