Abstract

A method for Boolean Satisfiability (SAT). The method comprises using a variable decision heuristic in a SAT algorithm and pruning the search space of SAT using said decision heuristic. The decision heuristic is based on partitioning a conjunctive normal form (CNF) of a Boolean formula corresponding to the SAT and the partitioning is induced by a separator set. An image computaion method that uses the disclosed method for solving the SAT.
