# How does answer set programming work?

## How does answer set programming work?

Abstract. Answer set programming is an approach to knowledge representation and reasoning. Knowledge is represented as answer set programs, and reasoning is performed by answer set solvers. Answer set programming enables default reasoning, which is required in commonsense reasoning.

Answer set programming (ASP) is a form of declarative pro- gramming oriented towards difficult search problems. As an outgrowth of research on the use of nonmonotonic reason- ing in knowledge representation, it is particularly useful in knowledge-intensive applications.

What is a stable model logic programming?

The concept of a stable model, or answer set, is used to define a declarative semantics for logic programs with negation as failure. This is one of several standard approaches to the meaning of negation in logic programming, along with program completion and the well-founded semantics.

### What is Prolog used for?

Prolog is a logic programming language that is used to create artificial intelligence. In order to come up with a query, or end goal, an artificial intelligence written in Prolog will analyze the relationship between a fact, a statement that is true, and a rule, which is a conditional statement.

What is sets and examples?

A set is a collection of elements or numbers or objects, represented within the curly brackets { }. For example: {1,2,3,4} is a set of numbers.

How do you apply sets in real life?

More scientifically, a set is a collection of well-defined objects. Apart from their mathematical usage, we use sets in our daily life….Let’s check some everyday life examples of sets.

1. In Kitchen. Kitchen is the most relevant example of sets.
2. School Bags.
3. Shopping Malls.
4. Universe.
5. Playlist.
6. Rules.
7. Representative House.

## What does programming in a logic programming language consist of?

Any program written in a logic programming language is a set of sentences in logical form, expressing facts and rules about some problem domain. Major logic programming language families include Prolog, answer set programming (ASP) and Datalog.

What is the full form of Fortran?

By The Editors of Encyclopaedia Britannica | View Edit History. FORTRAN, in full Formula Translation, computer programming language created in 1957 by John Backus that shortened the process of programming and made computer programming more accessible.

What is the meaning of Answer Set Programming?

Answer set programming. Answer set programming ( ASP) is a form of declarative programming oriented towards difficult (primarily NP-hard) search problems. It is based on the stable model (answer set) semantics of logic programming. In ASP, search problems are reduced to computing stable models, and answer set solvers —programs…

### Why do we use stable models in Answer Set Programming?

But the use of stable models in answer set programming provides a different perspective on such programs. In that programming paradigm, a given search problem is represented by a logic program so that the stable models of the program correspond to solutions.
