Topics of interest
------------------
This workshop aims at discussing and exchanging experience on the design, implementation, and optimization of logic, constraint (logic) programming systems, and other systems based on 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:

* Sequential implementation schemes (abstract machines, translation to other languages, etc.).
* Implementation of concurrent and distributed logic and constraint programming systems.
* Implementation of type inference and type checking systems for logic and constraint programming languages.
* Compile-time analysis and its application to code generation.
* Balance between compile-time effort and run-time machinery, dynamic compilation.
* Interaction between high-level optimizations / transformations / specialization and low-level issues.
* Memory management and garbage collection issues.
* Indexing techniques and optimizations for large size programs.
* Optimizations for program generated logic and constraint programs.
* Implementation of logic engines in functional and object oriented languages.
* Embedding of logic and constraint programming engines in multi-paradigm systems.
* Implementation techniques for alternative logic engines and inference mechanisms (ASP, SAT, QSAT, DL etc.).
* Implementation of theorem provers, proof assistants and logic based natural language processing systems.
* Implementation of object and agent-oriented extensions to logic and constraint programming languages.
* Object and module systems.
* Design and implementation of declarative I/O concepts for logic and constraint programming languages.
* Implementations and ports of logic and constraint programming systems for mobile phones and netbooks.
* Documenting, debugging, testing, and profiling tools for logic and constraint programming systems.

Workshop Goals
--------------
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.

History
-------
CICLOPS'09 continues a tradition of successful workshops on Implementations of Logic Programming Systems, previously held 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), Mumbai (2003), Saint Malo (France, 2004), Sitges (Spain, 2005), Seattle (U.S.A., 2006), Porto (Portugal, 2007), Udine (Italy, 2008).
