This ebook celebratesthe twenty fifth anniversaryof GULP—the Italian Associationfor LogicProgramming.Authored through Italian researchersat the forefront in their ?elds, it provides an updated survey of a wide choice of themes in common sense programming, making it an invaluable reference for either researchers and scholars. in the course of its 25-year lifestyles, GULP has organised a variety of nationwide and overseas actions, together with either meetings and summer time faculties. it's been particularly lively in aiding and inspiring younger researchers, via delivering scholarships for GULP occasions and awarding extraordinary disser- tions. WeintheinternationallogicprogrammingcommunitylookuponGULPwith a mix of envy, admiration and gratitude. we're happy to wait its meetings and summer season colleges, the place we will be able to know about scienti?c advances, meet up with outdated associates and meet younger scholars. it's an honour for me to recognize our appreciation to GULP for its striking contributions to our ?eld and to precise our greatest needs for its carrying on with prosperity sooner or later. March 2010 Robert Kowalski Imperial collage London Preface On June 18, 1985, a gaggle of pioneering researchers, together with representatives from undefined, nationwide study labs, and academia, attended the constituent meeting of the gang of researchers and clients of good judgment Programming (GULP) organization. That used to be the place to begin of an extended experience in technology, that 1 we're nonetheless experiencing 25 years later. This quantity celebrates this crucial event.

Durch kostengünstige Multiprozessor-Desktoprechner, Cluster von desktops und Innovationen wie die Hyperthreading-Technologie oder Multicore-Prozessoren sind parallele Rechenressourcen allgegenwärtig. Die effiziente Ausnutzung dieser parallelen Rechenleistung ist jedoch nur durch den Einsatz paralleler Programmiertechniken möglich, die sich damit in alle Bereiche der Softwareerstellung ausbreiten.

Example text
Bn is equivalent to the set of clauses {H :−B1 , . . , H :−Bn }. Therefore the following. Definition 12. Let c = H :−B1 , . . , Bn ∈ C. Krom(c) = {H :−B1 , . . , H :−Bn }. The Krom operator, which transforms (equivalence classes of) clauses into sets of binary clauses, is extended in the obvious way to subsets of C. Definition 13. Let I, J ⊆ C. I ∼pt J iff Krom(I) = Krom(J). ∼pt is a congruence wrt infinite unions and the operator Γ , therefore we have the usual definition of the semantics as instance of the scheme.
Definition 10. Let I, J ⊆ C. I ∼(Ω,s) J iff I ∩ C Ω is weakly subsumption equivalent to J ∩ C Ω . ∼(Ω,s) is a congruence wrt infinite unions and wrt the Γ operator and therefore, we obtain automatically from the scheme for any program P , F(Ω,s) by using ∼(Ω,s) as ∼. We have the following result. Lemma 5. Let P, Q be (finite) programs. P ≈(Ω,s) Q iff F(Ω,s) (P ) = F(Ω,s) (Q). 26 A. C. Meo Note that the previous result holds also for infinite programs which contain only finitely many function symbols.
