First Call for Provers
CoCo 2016
5th Confluence Competition
the week of September 4-10, 2016
Obergurgl, Austria
http://coco.nue.riec.tohoku.ac.jp/2016/
======================================================================
Confluence provides a general notion of determinism and has been
conceived as one of the central properties of rewriting. Confluence
had been investigated in several formalisms of rewriting such as
first-order rewriting, lambda-calculi, higher-order rewriting,
constrained rewriting and conditional rewriting. In recent years the
focus in confluence research has shifted towards the development of
automatable techniques for confluence proofs. The confluence
competition aims to foster the development of techniques for
proving/disproving confluence automatically by setting up a dedicated
competition among confluence tools.
The 5th Confluence Competition (CoCo 2016) will run ***live*** during
the 5th International Workshop on Confluence (IWC 2016), collocated
with Computational Logic in the Alps (CLA 2016) in Obergurgl, Austria.
The following categories will be run:
* TRS: confluence of first-order term rewrite systems
* CTRS: confluence of conditional term rewrite systems
* CPF: certification
* HRS: confluence of higher-order term rewrite systems
Besides these categories, new categories will be considered if there
are tools and problems dedicated to those categories. We welcome
requests for categories. Demonstration categories are for demonstrating new
attempts and/or merits of particular tools. Submissions of new
confluence problems are also welcome. For more information including
examples of new categories to be considered, platforms, competition
rules and problems, see the webpage of CoCo 2016 indicated above.
IMPORTANT DATES:
* request for competition categories February 28, 2016
* request for demonstration categories June 30, 2016
* tool registration August 21, 2016
* tool submission August 28, 2016
* problem submission August 30, 2016
* competition TBA (on the week of September 4-10, 2016)
REQUEST FOR NEW CATEGORIES:
Request for new categories is via the contact email address. Please send
the following information at your earliest convenience:
* category type (competition category or demonstration category)
* description of problems and semantics (rewrite steps, confluence, etc.)
together with adequate references
* a proposal of the input format (if necessary)
Requests for new categories may be rejected for technical reasons.
SUBMISSION OF NEW PROBLEMS:
Submissions of new confluence problems are welcome. Please use the web
interface of Cops (Confluence Problems) database linked from the
webpage of CoCo 2016.
REGISTRATION/SUBMISSION:
Tool registration is via the easychair. Every tool registration should
also contain a one page system description. Tool submission will be
via StarExec.
