The concept of anti-link is defined, and useful equivalence-preserving operations on propositional formulas based on anti-links are introduced. These operations eliminate a potent...
In this paper we develop a generic declarative diagnoser for normal logic programs that is based on tree search. The soundness and the completeness of the diagnoser are proved. The...
This paper shows a multisequential model to exploit OR parallelism on distributed memory systems. It presents an implementation of the incremental copy mechanism oriented to distr...
In Prz91], Przymusinski introduced the partial (or 3-valued) stable model semantics which extends the (2-valued) stable model semantics dened originally by Gelfond and Lifschitz G...
We present the design and the implementation of clp(B): a boolean constraint solver inside the Constraint Logic Programming paradigm. This solver is based on local propagation meth...
