                  Last Call for Papers (deadline: July 8th)

                              CICLOPS 2005
Colloquium on Implementation of Constraint and LOgic Programming Systems

                            October 5, 2005
                        Sitges (Barcelona) Spain

                     Satellite workshop of ICLP 2005


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,
* 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

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 webpage.

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
wokshop webpage 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.
