Method of analytic tableaux — A graphical representation of a partially built propositional tableau In proof theory, the semantic tableau (or truth tree) is a decision procedure for sentential and related logics, and a proof procedure for formulas of first order logic. The… … Wikipedia
Look-ahead (backtracking) — In backtracking algorithms, look ahead is the generic term for a subprocedure that attempts to foresee the effects of choosing a branching variable to evaluate or one of its values. The two main aims of look ahead are to choose a variable to… … Wikipedia

DPLL algorithm — The Davis–Putnam–Logemann–Loveland (DPLL) algorithm is a complete, backtracking based algorithm for deciding the satisfiability of propositional logic formulae in conjunctive normal form, i.e. for solving the CNF SAT problem. It was introduced in … Wikipedia
Local consistency — In constraint satisfaction, local consistency conditions are properties of constraint satisfaction problems related to the consistency of subsets of variables or constraints. Several such conditions exist, the most known being node consistency,… … Wikipedia
Backjumping — In backtracking algorithms, backjumping is a technique that reduces search space, therefore increasing efficiency. While backtracking always goes up one level in the search tree when all values for a variable have been tested, backjumping may go… … Wikipedia
