2. Boolean satisfiability problem - Wikipedia

   en.wikipedia.org/wiki/Boolean_satisfiability_problem

   If the answer is "no", the formula is unsatisfiable. Otherwise, the question is asked on the partly instantiated formula Φ{x 1 =TRUE}, that is, Φ with the first variable x 1 replaced by TRUE, and simplified accordingly. If the answer is "yes", then x 1 =TRUE, otherwise x 1 =FALSE. Values of other variables can be found subsequently in the ...

3. Literal (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Literal_(computer_programming)

   In computer science, a literal is a textual representation (notation) of a value as it is written in source code. [1] [2] Almost all programming languages have notations for atomic values such as integers, floating-point numbers, and strings, and usually for Booleans and characters; some also have notations for elements of enumerated types and compound values such as arrays, records, and objects.

4. Literal (mathematical logic) - Wikipedia

   en.wikipedia.org/wiki/Literal_(mathematical_logic)

   In mathematical logic, a literal is an atomic formula (also known as an atom or prime formula) or its negation. [1] [2] The definition mostly appears in proof theory (of classical logic), e.g. in conjunctive normal form and the method of resolution. Literals can be divided into two types: [2] A positive literal is just an atom (e.g., ).

5. DPLL algorithm - Wikipedia

   en.wikipedia.org/wiki/DPLL_algorithm

   The basic backtracking algorithm runs by choosing a literal, assigning a truth value to it, simplifying the formula and then recursively checking if the simplified formula is satisfiable; if this is the case, the original formula is satisfiable; otherwise, the same recursive check is done assuming the opposite truth value.

6. Consensus theorem - Wikipedia

   en.wikipedia.org/wiki/Consensus_theorem

   The consensus or consensus term of two conjunctive terms of a disjunction is defined when one term contains the literal and the other the literal ¯, an opposition. The consensus is the conjunction of the two terms, omitting both a {\displaystyle a} and a ¯ {\displaystyle {\bar {a}}} , and repeated literals.
