AKL in der Krise
No full texthttp://blog.arthistoricum.net/akl-in-der-krise Die Krise des AKL zeigt exemplarisch die Entfremdung zwischen Wissenschaft und Verlagswesen. Verlage entledigen sich unter dem Diktat betriebswirtschaftlicher Rentabilitätskriterien zunehmend ihrer eigentlichen Aufgabe der Qualitätssicherung im Wissenschaftsbetrieb. Gleichzeitig möchten sie jedoch vom „Content“ profitieren, den andere unentgeltlich produzieren und weiterhin Abos teuer an Bibliotheken verkaufen
The implementation of AKL(FD)
Get PDFAKL(FD) is an integration of (an extension of) the finite domain constraint system FD in AKL, a deep concurrent constraint programming language [CJH94]. In this paper we describe the implementation of the FD solver and its adaptation to the generic constraint interface of the AGENTS implementation of AKL. We also describe compilation techniques used by the AKL(FD) compiler. 1 Introduction Conceptually, a concurrent constraint programming (CCP [SRP91]) language is an ideal vehicle for constraint programming. The expressiveness of the constraint solver can be extended by user-defined entailment-driven propagation rules that execute concurrently and cooperate with the constraint solver. However, to offer an orthogonal combination of constraint programming with the other paradigms offered by CCP---concurrent, relational, functional, object-oriented, : : : ---the language must be deep. Being deep means having a hierarchy of constraint stores, where a computation need not be affected by th..
Some Formal Aspects of AKL
No full textThe Agents Kernel Language allows committed choice
programming as well as nondeterministic logic programming
based on the Andorra principle (and combinations of these),
with a considerable degree of parallelism. In the present
report the AKL computation model is formally defined and
soundness and completeness results for a logical subset of
AKL are presented. The computation model is extended to cover
ports, a medium of communication used in AKL, and the
solution collecting operation bagof. These extensions
preserve the basic character of the computation model, and in
particular the role played by the constraint theory.
Declarative interpretations of these constructs are
introduced, and the limitations of these readings are
discussed. Finally, the confluence of strongly fair (possibly
infinite) computations in a different subset of AKL is
proved

AKL - A Multiparadigm Programming Language
No full textThis thesis reports on an investigation into principles for combining the constraint solving and don't know nondeterministic capabilities of Prolog and the constraint logic programming languages with the process-describing capabilities of concurrent logic languages such as GHC. The result, AKL, is a coherent language supporting multiple programming paradigms, such as concurrent, object-oriented, functional, logic, and constraint programming. In addition, AKL offers a large potential for automatic parallel execution
Structural Operational Semantics for AKL
No full textThe Andorra Kernel Language (AKL) is a concurrent constraint programming language. It can be seen as a general combination of logic programming languages such as Prolog, GHC, and Parlog, the first of which provides don't know nondeterminism, and the last two of which are concurrent logic programming languages. The constraint system is an independent parameter of the language description. In this paper, we revisit the description of Janson and Haridi [10], adding the formal machinery which is necessary in order to completely formalize the control of the computation model. To this we add a formal description of the transformational semantics of AKL. The semantics is a set of or-trees which also captures infinite computations. 1 Introduction The Andorra Kernel Language (AKL) is a general combination of search-oriented don't know nondeterministic logic programming languages, such as Prolog, and process-oriented concurrent logic programming languages, such as GHC, Parlog, and others [18, 6..

Towards an Analysis Tool for AKL
No full textWe present a method for analysis of AKL in the spirit of abstract interpretation that strictly separates the setting up of the abstract semantic equations and the solving of these equations. The fact that AKL has concurrent semantics makes this separation particularly attractive. This document reports work in progress. It is deliverable number D.WP.1.6.1.M1.1 in the ESPRIT project ParForce 6707. A final report on the work is expected in July 1994. 2 1. Introduction In order to provide information guiding a more efficient compilation of the language AKL two analysis frameworks have been specified and they have both been implemented in AKL. The analysis frameworks are based on fixpoint semantics, i.e. a set of semantic equations is set up and solved using fixpoint iteration techniques. This allows a clear division of the different parts. It also enables experimentation with different strategies for the solution of the analysis problem and also replacement of the domains with relative e..
