Logic transformation and coding theory-based frameworks for Boolean satisfiability

Abstract

This paper proposes a new framework to the solution of Boolean Satisfiability. The first approach is based on certain structural analysis using circuit representation. Here, we convert the given CNF into multilevel circuits based on testability-driven transformation and optimization, and then apply a test technique developed by the authors to verify SAT. This test technique is based on the concepts developed by an earlier-proposed verification tool, VERILAT. Certain algebraic coding theory results are then derived that provide a lower bound on the number of solutions to SAT problems. These proposed frameworks have a real potential for providing new theoretical insights.
