**Constraint learning**— In constraint satisfaction backtracking algorithms, constraint learning is a technique for improving efficiency. It works by recording new constraints whenever an inconsistency is found. This new constraint may reduce the search space, as future… …72

**Gödel's incompleteness theorems**— In mathematical logic, Gödel s incompleteness theorems, proved by Kurt Gödel in 1931, are two theorems stating inherent limitations of all but the most trivial formal systems for arithmetic of mathematical interest. The theorems are of… …73

**Entailment**— For other uses, see Entail (disambiguation). In logic, entailment is a relation between a set of sentences (e.g.,[1] meaningfully declarative sentences or truthbearers) and a sentence. Let Γ be a set of one or more sentences; let S1 be the… …74

**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… …75

**ECONOMIC AFFAIRS**— THE PRE MANDATE (LATE OTTOMAN) PERIOD Geography and Borders In September 1923 a new political entity was formally recognized by the international community. Palestine, or Ereẓ Israel as Jews have continued to refer to it for 2,000 years,… …76

**Paraconsistent logic**— A paraconsistent logic is a logical system that attempts to deal with contradictions in a discriminating way. Alternatively, paraconsistent logic is the subfield of logic that is concerned with studying and developing paraconsistent (or… …77

**Default logic**— is a non monotonic logic proposed by Raymond Reiter to formalize reasoning with default assumptions. Default logic can express facts like “by default, something is true”; by contrast, standard logic can only express that something is true or that …78

**Tu quoque**— (IPA: IPA|/tu ˈkwoʊkwɛ/, Latin for You, too or You, also ) is a Latin term used to mean an accusation of hypocrisy. The argument states that a certain position is false or wrong and/or should be disregarded because its proponent fails to act… …79

**Witness impeachment**— Witness impeachment, in the law of evidence, is the process of calling into question the credibility of an individual who is testifying in a trial. There are a number of ways that a witness may properly be impeached, and several ways that,… …80

**Ω-consistent theory**— In mathematical logic, an ω consistent (or omega consistent, also called numerically segregativeW.V.O. Quine, Set Theory and its Logic ] ) theory is a theory (collection of sentences) that is not only (syntactically) consistent (that is, does not …
