Mathematical Background

Mathematical Background. Appendix A. Boolean Logic Wffs. A wff is any string that is formed according to the following rules:. A propositional symbol (or variable) is a wff. If P is a wff, then ? P is a wff. If P and Q are wffs, then so are: P ? Q , P ? Q , P ? Q , and P ? Q .

SAT: Propositional Satisfiability

SAT: Propositional Satisfiability. A tutorial. What is SAT?. Given a propositional formula in CNF, find an assignment to Boolean variables that makes the formula true:. ? 1 = (x 2 ? x 3 ) ? 2 = ( ? x 1 ? ?x 4 ) ? 3 = ( ? x 2 ? x 4 ) A = {x 1 =0, x 2 =1, x 3 =0, x 4 =1}.
