We show that the family of stable models of a recursive predicate logic program is, up to a recursive coding, a class (ie an effectively closed set)
In this paper we investigate and solve the problem classifying the Tur- ing complexity of stable models of finite and recursive predicate logic programs.

The concept of a stable model, or answer set, is used to define a declarative semantics for logic programs with negation as failure.
Abstract. Stable models of logic programs have been studied by many researchers, mainly because of their role in the foundations of answer set programming.
The stable model semantics is defined for a logic program II, if II has exactly one stable model, and it declares that model to be the canonical model of II. ...
Every positive program has a unique stable model (even a program containing several predicate constants, as will be discussed later.)

The family of all stable models for a logic program has a surprisingly simple overall structure, once two naturally occuring orderings are made explicit.
Sep 1, 2017 · We present a method for computing stable models of normal logic programs, ie, logic programs extended with negation, in the presence of predicates with ...
