Preliminary Call for Papers

------------------------------------------------------------------ CICLOPS 2005 Colloquium on Implementation of Constraint and LOgic Programming Systems

October 5, 2005 Sitges (Barcelona) Spain

Satellite workshop of ICLP 2005 ------------------------------------------------------------------

http://www.dcc.fc.up.pt/ciclops05

Topics of interest ------------------

The workshop aims at discussing and exchanging experience on the design, implementation, and optimization of logic and constraint (logic) programming systems, or systems intimately related to logic as a means to express computations. Preference will be given to the analysis and description of implemented (or under implementation) systems and their associated techniques, problems found in their development or design and steps taken towards the solutions.

The workshop topics include, but are not limited to:

* Implementation of standard/alternative sequential models (generalization and modification of the WAM, translation to lower-level and/or general-purpose languages, etc); * Implementation of parallel/concurrent models; * Interaction between high-level optimisations/transformations and low-level issues; * Compile-time analysis and its application to code generation; * Balance between compile-time effort and run-time machinery; * Memory management, indexing, and garbage collection issues; * Profiling tools and performance evaluation; * Implementation techniques for declarative programming paradigms with basis on, or extending, logic and constraint programming, such as non-monotonic reasoning, inductive logic programming, natural language processing systems, etc; * Software design with and for LP/CP systems: components, patterns, etc; * Design and implementation of programming environments; * Experiences from using systems in real-life applications.

Workshop Relevance ------------------

The last years have witnessed continuous progress in the technology available both for academic and commercial computing environments. Examples include improved processor performance, increased memory capacity and bandwidth, faster networking technology, and operating system support for cluster computing. These improvements, combined with recent advances in compilation and implementation technologies, are causing high-level languages to be regarded as good candidates for programming complex, real world applications.

Logic Programming and Constraint Programming, in particular, seem to offer one of the best options, as they couple a high level of abstraction and a declarative nature with an extreme flexibility in the design of their implementations and extensions and of their execution model. This flexibility is the key to, for example, the implicit exploitation of parallelism, allowing immediate and transparent reuse of logic and constraint programs written for sequential machines, without compromising efficiency. Moreover, implementations which reach good performance in terms of speed and memory consumption make declarative languages and systems amenable to develop non-trivial applications.

We hope that the workshop will provide a meeting point and bring together people working on implementation technology for different aspects of logic and constraint-based languages and systems, in order to promote the exchange of ideas and feedback on recent developments. The workshop continues a tradition of successful workshops on Implementations of Logic Programming Systems, previously held with in Budapest (1993), Ithaca (1994) and Portland (1995), the Compulog Net workshops on Parallelism and Implementation Technologies held in Madrid (1993 and 1994), Utrecht (1995) and Bonn (1996), the Workshop on Parallelism and Implementation Technology for (Constraint) Logic Programming Languages held in Port Jefferson (1997), Manchester (1998), Las Cruces (1999), and London (2000), and recently the Colloquium on Implementation of Constraint and LOgic Programming Systems in Paphos (2001), Copenhagen (2002), Mumbai (2003), and Saint-Malo (2004), and the CoLogNet Workshops on Implementation Technology for Computational Logic Systems held in Madrid (2002), and Pisa (2003).

Submission Information ----------------------

Authors are invited to submit papers written in English and not exceeding 12 pages. Submissions should contain full return mail, email address (if applicable) and fax number (if applicable) of the contact author. To speed up the process of refereeing, authors are requested to submit their paper in Postscript or PDF using a submission form located at the workshop web-page.

In order to obtain homogeneous workshop proceedings, authors of accepted papers will be requested to send the sources to the organizers. We strongly encourage the use of LaTeX style files, both in the preparation of submissions and, specially, for the final version (please consult the template and style files located at the workshop web-page to prepare your paper). Authors who wish to prepare papers in formats other than LaTeX are kindly requested to contact the organization beforehand in order to make sure that we have available the right tools to process the files (if needed), or in order to receive detailed format instructions otherwise.
