PALS: An Or-Parallel Implementation of Prolog on Beowulf Architectures
This paper describes the development of the PALS system, an implementation of Prolog that efficiently exploits or-parallelism on share-nothing platforms. PALS makes use of a novel ...

On a Tabling Engine That Can Exploit Or-Parallelism
Tabling is an implementation technique that improves the declarativeness and expressiveness of Prolog by reusing solutions to goals. Quite a few interesting applications of tabling...

A Multi-adjoint Logic Approach to Abductive Reasoning
Multi-adjoint logic programs has been recently introduced [9, 10] as a generalization of monotonic logic programs [2, 3], in that simultaneous use of several implications in the ru...

Fixed-Parameter Complexity of Semantics for Logic Programs
In the paper we establish the xed-parameter complexity for several parameterized decision problems involving models, supported models and stable models of logic programs. We also e...

Alternating Fixed Points in Boolean Equation Systems as Preferred Stable Models
We formally characterize alternating fixed points of boolean equation systems as models of (propositional) normal logic programs. To this end, we introduce the notion of a preferr...

An Order-Sorted Resolution with Implicitly Negative Sorts
We usually use natural language vocabulary for sort names in order-sorted logics, and some sort names may contradict other sort names in the sort-hierarchy. These implicit negation...
