Observed Lower Bounds for Random 3-SAT Phase Transition Density Using Linear Programming
We introduce two incomplete polynomial time algorithms to solve satisfiability problems which both use Linear Programming (LP) techniques. First, the FlipFlop LP attempts to simul...

MFSAT: A SAT Solver Using Multi-Flip Local Search
Local search-based methods of SAT solving have received a significant attention in the last decade. All local search-based methods choose the next truth assignment by flipping t...

VARSAT: Integrating Novel Probabilistic Inference Techniques with DPLL Search
Probabilistic inference techniques can be used to estimate variable bias, or the proportion of solutions to a given SAT problem that fix a variable positively or negatively. Metho...

The Optimality of a Fast CNF Conversion and its Use with SAT
Despite the widespread use and study of Boolean satisfiability for a diverse range of problem domains, encoding of problems is usually given to general propositional logic with li...
