CICLOPS 2017: Call for Papers and Talk Proposals

16th International Colloquium on Implementation of Constraint and LOgic Programming Systems 

18 July 2018
Oxford, UK

Co-located with ICLP’18 and FLoC. 

Important Dates 

  • Paper submission: 29 April 2018
  • Author Notification: 11 May 2018
  • Camera-ready Copy: 25 June 2018 

 Dates are intended as Anywhere on Earth. 

Aims and Scope 

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.
  • Novel compilation methods to modern hardware (e.g. GPUs). 

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. 

Paper Submissions 

Submission Categories: The workshop welcomes a range of different submissions, including contributions to theory, reports of interesting applications, reports of work in progress, experience papers, suggestions for new challenging problems, system descriptions, comparison and discussion papers, and improvements to known results/proofs/implementations. We distinguish several different categories:

  • Novel Research: Abstracts, Short and Long Papers: These are works on novel research contributions at any stage in the research process (hence the choice of format). These can also be extended papers of short technical communications at ICLP.
  • Talk Proposals: Abstracts: These are proposals for talks about papers already submitted or presented elsewhere or has appeared in a journal. For instance, these can be extended presentations of the short technical communication talks at ICLP.

For all accepted submissions, at least one author is required to attend the workshop and give a presentation of 30 minutes including discussion.

Submission Procedure: All submissions (talk abstracts, short and long papers) must be written in English and use Springer’s LNCS format. Abstracts are 1-2 pages, short papers 5-6, and long papers up to 15 pages.

New Reviewing Procedure

To provide a fast notification, before the common FLoC deadline, the reviewing will proceed in two stages: In the first phase the program chair and program committee perform a quick review of the papers to determine their suitability for acceptance. The authors are notified of this decision on May 11.

In the second phase, the program committee performs a more in-depth review, to provide the authors with useful feedback to revise their submission. The authors receive these reviews on May 25 and have until June 25 to produce their final copy.


The proceedings are informal and will be available from the CICLOPS website and as a KU Leuven technical report.
