WebOf course, they get stumped by some formulae that are much smaller than that, but many variables and many clauses are not the main obstacle. All in all, the Tseitin transformation is a practical, widely adopted approach to reducing Boolean circuits to CNF. There are variants of the transformation that occasionally perform a bit better. WebAug 7, 2024 · We discuss a transformation of formulas that obtains CNF with only linear blowup in size. However, there is a cost of saving the space.
