A compound proposition is satisfiable if there exists at least one truth assignment that makes it true.
Conjunctive Normal Form (CNF) is a representation of a compound proposition as a conjunction of clauses, where each clause is a disjunction of literals.
The SAT problem can be applied to various practical scenarios, including solving Sudoku puzzles, by encoding the problem as a compound proposition.
A problem of determining whether a given compound proposition has at least one truth assignment that makes it true.
A way of structuring a logical expression as a conjunction of clauses, where each clause consists of disjunctions of literals.
A disjunction of literals within a CNF, representing a part of the overall compound proposition.
A variable or the constants true or false, which can be used in clauses.
