Logic programming. Logic programming is a programming, database and knowledge representation paradigm based on formal logic. A logic program is a set of sentences in logical form, representing knowledge about some problem domain. Computation is performed by applying logical reasoning to that knowledge, to solve problems in the domain.
Logic programming is a programming, database and knowledge representation paradigm that is based on formal logic. A logic program is a set of sentences about some problem domain. Computation is performed by applying logical reasoning to solve problems in the domain. Major logic programming language families include Prolog, Answer Set ...
Propositional formula. In propositional logic, a propositional formula is a type of syntactic formula which is well formed. If the values of all variables in a propositional formula are given, it determines a unique truth value. A propositional formula may also be called a propositional expression, a sentence, or a sentential formula.
The propositional calculus[ a ] is a branch of logic. [ 1 ] It is also called propositional logic, [ 2 ]statement logic, [ 1 ]sentential calculus, [ 3 ]sentential logic, [ 1 ] or sometimes zeroth-order logic. [ 4 ][ 5 ] It deals with propositions [ 1 ] (which can be true or false) [ 6 ] and relations between propositions, [ 7 ] including the ...
Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the study of deductively valid inferences or logical truths. It examines how conclusions follow from premises based on the structure of arguments alone, independent of their topic and content.
Algorithmic logic is a calculus of programs that allows the expression of semantic properties of programs by appropriate logical formulas.It provides a framework that enables proving the formulas from the axioms of program constructs such as assignment, iteration and composition instructions and from the axioms of the data structures in question see Mirkowska & Salwicki (1987), Banachowski et ...
Syntax and semantics of logic programming. Logic programming is a programming paradigm that includes languages based on formal logic, including Datalog and Prolog. This article describes the syntax and semantics of the purely declarative subset of these languages. Confusingly, the name "logic programming" also refers to a specific programming ...
Situation calculus. The situation calculus is a logic formalism designed for representing and reasoning about dynamical domains. It was first introduced by John McCarthy in 1963. [1] The main version of the situational calculus that is presented in this article is based on that introduced by Ray Reiter in 1991.
