Introduction

    The CHR 2013 Workshop will be held on July 11th and 12th, 2013 in Berlin
    (Germany) at the occasion of the 3rd International Summer School on CHR.
    More information on the venue and the co-located summer school can be
    found on the summer school website (http://met.guc.edu.eg/CHR2013/).

    The Constraint Handling Rules (CHR) language has become a major declara-
    tive specification formalism and implementation language for constraint
    reasoning algorithms and applications. Algorithms specified using infe-
    rence rules, rewrite rules, sequents, proof rules, or logical axioms can
    often be directly written in CHR. Its clean semantics facilitates pro-
    gram design, analysis, and transformation. For more information, please
    visit the CHR website (http://dtai.cs.kuleuven.be/CHR/).

    The aim of the CHR workshop series is to stimulate and promote interna-
    tional research and collaboration on topics related to the CHR language.
    The workshop is a lively, friendly forum for presenting and discussing
    new results, interesting applications, and work in progress.
    Previous Workshops on Constraint Handling Rules were organized in 2004
    in Ulm (Germany), in 2005 in Sitges (Spain) at ICLP, in 2006 in Venice
    (Italy) at ICALP, in 2007 in Porto (Portugal) at ICLP, in 2008 in Hagen-
    berg (Austria) at RTA, in 2009 in Pasadena (California, US) at ICLP, in
    2010 in Edinburgh (Scotland, UK) at ICLP, in 2011 in Cairo (Egypt), at
    the 2nd CHR summer school, and in 2012 in Budapest (Hungary) at ICLP.


Topics of Interest

    The workshop calls for full papers and short papers describing ongoing
    work on any aspect of CHR and related approaches. The following topics
    are relevant (this list is non-exhaustive):

    - (Logical) Algorithms
    - Applications
    - Constraint Solvers
    - Critical Assessment
    - Expressiveness and Complexity
    - Implementations and Optimization
    - Language Extensions (Types, Modules,...)
    - Mutual inspiration from related areas such as
        Answer Set Programming, (Term) Rewriting Systems, ...
    - Program Analysis
    - Program Transformation and Generation
    - Programming Environments (Debugging)
    - Programming Pearls
    - Programming Tools
    - Retractable Constraints
    - Semantics
    - System Descriptions


Important dates

    - Paper submission deadline: May 8th, 2013
    - Notification of acceptance: June 8th, 2013
    - Final version due: June 23rd, 2013
    - Workshop date: July 11th and 12th, 2013


Submission Information

    The two categories for submissions are:

     - full papers for describing technically sound, innovative ideas that
       can advance the state of the art of CHR;

     - short papers, for ongoing work not yet ready for full publication
       and research project overviews.

    All papers must describe original, previously unpublished research, and
    must not simultaneously be submitted for publication elsewhere.
    They must be written in English. Technical papers must not exceed 15
    pages. The limit for short papers is 8 pages, as is the standard page
    limit for application papers, and system and tool papers. However,
    particularly strong contributions in the latter two areas may be
    submitted as technical paper as well.

    All papers must be in the Springer LNCS format. General information
    about the Springer LNCS series and the LNCS authors' instructions are
    available at the Springer LNCS home page
    (http://www.springer.com/computer/lncs?SGWID=0-164-7-72376-0).

    Submissions must be made via the EasyChair submission system, available
    at http://www.easychair.org/conferences/?conf=chr2013
