Faster sat solving with better cnf generation

WebThe SAT-based approach divides into three steps: encoding, preprocessing, and search. It is often argued that by encoding arbitrary Boolean formulas in conjunctive normal form … Webrange of benchmarks. The results demonstrate that: (i) the variable order gen-erated by our approach signiflcantly improves the performance of SAT solvers; (ii) time to derive this order is a fraction of the overall solving time. As a re-sult, our approach delivers faster performance (often, by orders of magnitude)
