The '''Boolean satisfiability problem''' (often abbreviated '''SAT''') is the problem of determining whether a given propositional formula has an assignment of truth values to its variables that makes the entire formula true. Despite its simplicity, SAT is the canonical [[NP-complete]] problem: every problem whose solutions can be verified in polynomial time reduces to SAT in polynomial time, as proved by the [[Cook-Levin Theorem|Cook-Levin theorem]].

SAT is typically studied in [[Conjunctive normal form|conjunctive normal form]] (CNF), where the formula is a conjunction of clauses, each clause being a disjunction of literals. The special case where each clause contains exactly three literals — '''3-SAT''' — remains NP-complete and is the standard form for theoretical analysis. In practice, modern [[SAT solver]]s routinely handle formulas with millions of variables and clauses, exploiting structure that worst-case analysis cannot capture.
