Jun 20, 2014 · iDQ is an instantiation-based DQBF (Dependency Quantified Boolean Formula) solver for input formules in DQDIMACS format.

The resulting solver iDQ [FKBV14] is the first publicly available DQBF solver. Similar to the Inst-Gen calculus and some instantiation-based QBF solving ...

Abstract—Dependency quantified Boolean formulas (DQBFs) are a powerful formalism, which subsumes quantified Boolean formulas (QBFs) and allows an explicit ...

Aug 10, 2022 · In this paper, we provide a formal definition for syntax and semantics of non-closed non-prenex DQBFs and prove useful properties enabling quantifier ...

From DQBF to QBF by Dependency Elimination. 327. While iDQ uses instantiation-based solving, i.e., it reduces deciding a DQBF to deciding a series of SAT ...

Abstract—We show how to solve dependency quantified Boolean formulas (DQBF) using a quantifier elimination strategy which yields.

▷ Instantiation. {`σ|D(var(`)) | ` ∈ C,var(`) ∈ E}. • σ total assignment ... We presented two decision procedures for DQBF based on definition extraction.
