Topics of interest
This workshop aims at discussing and exchanging experience on the design, implementation, and optimization of logic, constraint (logic) programming systems, and systems intimately related to logic as a means to express computations. Experience backed up by real implementations and their evaluation will be given preference, as well as descriptions of work in progress in that direction.
Topics include, but are not limited to:
- Standard and alternative sequential implementation schemes (e.g., generalization / modification of the WAM, translation to lower-level and/or general-purpose languages, etc.)
- Interaction between high-level optimizations / transformations / specialization and low-level issues.
- Compile-time analysis and its application to code generation.
- Low-level cost models to guide high-level optimizations.
- Memory management, indexing, and garbage collection issues.
- Balance between compile-time effort and run-time machinery.
- Implementation of parallel and concurrent logic and constraint programming systems.
- Implementation techniques for declarative programming paradigms with basis on, or extending, logic and constraint programming, such as non-monotonic reasoning, inductive logic programming, etc.
- Implementation of systems closely related to, or based on, logic, such as theorem provers and natural language processing systems.
- Performance evaluation of logic and constraint programming systems.
- User oriented tools for performance evaluation and profiling.
- 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.
Our intent is to bring together, in an informal setting, people involved in research on sequential and parallel implementation technologies for logic and constraint programming languages and systems, in order to promote the exchange of ideas and feedback on recent developments. We hope that the workshop will provide a meeting point for people working on implementation technology for different aspects of logic and constraint-based languages and systems.
Rationale and History
The last years have witnessed continuous progress in the technology available both for academic and commercial computing environments. Examples include more 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. Techniques aiming at achieving flexibility in the language design make powerful extensions easier to implement; on the other hand, implementations which reach good performance in terms of speed and memory consumption make declarative languages and systems amenable to develop non-trivial 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 adaptability is key to, for example, the implicit exploitation of alternative execution strategies tailored for different applications (e.g., for domain-specific languages) without jeopardizing efficiency unnecessarily.
This workshop continues a tradition of successful workshops on Implementations of Logic Programming Systems, previously held with in Budapest (1993) and Ithaca (1994), 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 more recently the Colloquium on Implementation of Constraint and LOgic Programming Systems in Paphos (Cyprus, 2001), Copenhagen (2002), and Mumbai (2003), and the CoLogNet Workshops on Implementation Technology for Computational Logic Systems held in Madrid (2002) and Pisa (2003).
Due to its very convenient European location, CICLOPS 2004 is also being used as the yearly CoLogNet workshop of the implementation area.
Authors are invited to submit papers written in English and not exceeding 12 pages. To speed up the process of refereeing, authors are requested to submit their paper in Postscript or PDF form using this page. Hard copies may be sent to the contact address below only if access to electronic media is not available; please contact the organizers beforehand if that is the case. Submissions should contain full return mail and email address (if applicable) and FAX number (if applicable) of the contact author. Prospective authors are kindly requested to first send an indication of interest together with a paper title and abstract, in plain text format, to the organizers at the e-mail address at the bottom of the page.
LaTeX style files are available via WWW at the Workshop web site. We strongly encourage their use, both in the preparation of submissions and, specially, for the final version. In order to obtain homogeneous workshop proceedings, authors of accepted papers will be requested to send the sources to the organizers. 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.
