Boolean satisfiability

WebThe Boolean satisfiability problem (B-SAT) is a problem solver containing binary variables connected by logical relations such as OR and AND using SAT formulas. In other words, it asks whether the variables of a given Boolean formula can be consistently replaced by the values TRUE or FALSE in such a way that the formula evaluates to TRUE. A decision problem is in NP if it can be solved by a non-deterministic algorithm in polynomial time. An instance of the Boolean satisfiability problem is a Boolean expression that combines Boolean variables using Boolean operators. An expression is satisfiable if there is some assignment of truth values to the variables that makes the entire expression true.
