Tseitin's encoding
WebJun 23, 2024 · So, applying a SAT solver to Tseitin’s encoding of a formula lets us obtain not only a yes/no decision but also a satisfying interpretation if the solver produces one. The key idea behind Tseitin’s encoding is to use new propositional variables, called auxiliary variables, to refer to the subformulas in the input formula \(f\).

( x_a), and ( x_b) in F are equivalent to the Tseitin encoding of the gate x = and(a;b).
