Model Counting for Dependency Quantified Boolean Formulas

AAAI 2026technical

Dependency Quantified Boolean Formulas (DQBF) generalize QBF by explicitly specifying which universal variables each existential variable depends on, instead of relying on a linear quantifier order. The satisfiability problem of DQBF is NEXP-complete, and many hard problems can be succinctly encoded

Knowledge Compilation for Incremental and Checkable Stochastic Boolean Satisfiability

IJCAI 2024poster

Knowledge compilation has proven effective in (weighted) model counting, uniquely supporting incrementality and checkability. For incrementality, compiling an input formula once suffices to answer multiple queries, thus reducing the total solving effort. For checkability, the compiled formula is ame…
