Chaff (SAT Solver)

Chaff is a high-performance SAT solver used to determine if a complex logical formula (expressed in propositional logic) can be satisfied, meaning if there’s some way to assign true or false values to variables to make the formula true. It employs advanced algorithms and heuristics, such as conflict-driven clause learning, to efficiently explore possible solutions by quickly pruning impossible options. Chaff is especially effective in fields like hardware verification and software testing, where swiftly solving large, intricate logical problems is essential. Its design emphasizes speed and scalability, making it a key tool in automated reasoning.
