CHR 2013

Tenth International Workshop on Constraint Handling Rules
Berlin, Germany — July 13th, 2013


The CHR 2013 Workshop will be held on July 13th, 2013 in Berlin (Germany) at the occasion of the Third International Summer School on CHR.

The Constraint Handling Rules (CHR) language has become a major declarative specification formalism and implementation language for constraint reasoning algorithms and applications. Algorithms are often specified using inference rules, rewrite rules, sequents, proof rules, or logical axioms that can be directly written in CHR. Its clean semantics facilitates program design, analysis, and transformation. See the CHR website for more information.

The aim of the CHR workshop series is to stimulate and promote international research and collaboration on topics related to the Constraint Handling Rules 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 Hagenberg (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.
