Aggregate Functions in Disjunctive Logic Programming: Semantics, Complexity, and Implementation in DLV
Disjunctive Logic Programming (DLP) is a very expressive formalism: it allows to express every property of finite structures that is decidable in the complexity class ¡£¢¤ (...

An Ordered Logic Program Solver
We describe the design of the OLPS system, an implementation of the preferred answer set semantics for ordered logic programs. The basic algorithm we propose computes the extended ...

Stable models and circumscription
The concept of a stable model provided a declarative semantics for Prolog programs with negation as failure and became a starting point for the development of answer set programmi...

A Default Approach to Semantics of Logic Programs with Constraint Atoms
We define the semantics of logic programs with (abstract) constraint atoms in a way closely tied to default logic. Like default logic, formulas in rules are evaluated using the cl...

A New Perspective on Stable Models
The definition of a stable model has provided a declarative semantics for Prolog programs with negation as failure and has led to the development of answer set programming. In th...
