The correct answer is: All of the mentioned.
Logic programming is a programming paradigm based on formal logic. It is a declarative programming paradigm, which means that the programmer specifies the desired results, not how to achieve them. Logic programming is often used for artificial intelligence applications, such as natural language processing and expert systems.
Logic programming is based on the idea of first-order logic. First-order logic is a formal system for representing knowledge. It consists of a set of symbols, called terms, and a set of rules, called axioms. Terms can be constants, variables, or functions. Axioms are statements that are always true.
In logic programming, programs are written as sets of clauses. A clause is a statement of the form:
- Head :- Body
The head is a predicate, which is a statement that is either true or false. The body is a list of predicates. The clause is true if the head is true whenever all of the predicates in the body are true.
For example, the following clause is a
