WRS06
The Sixth International Workshop on Reduction Strategies in Rewriting and Programming http://www.cs.pdx.edu/~antoy/wrs06/
The Seattle Sheraton Hotel and Towers, Seattle, Washington, August 11, 2006
Scope
The workshop intends to promote and stimulate international research and collaboration in the area of evaluation strategies. It encourages the presentation of new directions,developments and results as well as surveys and tutorials on existing knowledge in this area. Reduction strategies study which subexpression(s) of an expression should be selected for evaluation and which rule(s) should be applied. These choices affect fundamental properties of a computation such as laziness, strictness, completeness and need to name a few. For this reason some programming languages, e.g., Elan, Maude, *OBJ* and Stratego, allow the explicit definition of the evaluation strategy, whereas other languages,e.g., Clean, Curry, and Haskell, allow its modification. Strategies pose challenging theoretical problems and play an important role in practical tools such as theorem provers, model checkers and programming languages. In implementations of languages, strategies bridge the gap between operational principles, e.g., graph and term rewriting,narrowing and lambda-calculus, and semantics, e.g., normalization, computation of values and head-normalization. The previous editions of the workshop were: WRS 2001 (Utrecht, The Netherlands),WRS 2002 (Copenhagen, Denmark), WRS 2003 (Valencia, Spain), WRS 2004 (Aachen, Germany), and WRS 2005 (Nara, Japan).

Topics
Topics of interest include, but are not restricted to:
o theoretical foundations for the definition and semantic description of reduction strategies
o strategies in different frameworks such as term rewriting, graph rewriting, infinitary rewriting, lambda calculi, higher order rewriting, conditional rewriting, rewriting with built-ins, narrowing, constraint solving, etc.
o application of strategies to equational, functional, functional-logic programming languages
o properties of reduction strategies and corresponding computations, e.g., completeness, computability, decidability, complexity, optimality, normalization, cofinality, fairness, perpetuality, context-freedom, need, laziness, eagerness, strictness
o interrelations, combinations and applications of reduction under different strategies, e.g., evaluation mechanisms in programming languages, equivalence conditions for fundamental properties like termination and confluence, applications in modularity analysis, connections between strategies of different frameworks,etc.
o program analysis and other semantics-based optimization techniques dealing with reduction strategies
o rewrite systems, tools, implementations with flexible or programmable strategies as an essential concept or ingredient
o specification of reduction strategies in real languages strategies suitable to software engineering problems and applications tutorials and systems related to evaluation strategies
Submissions
Submissions must be original and not submitted for publication elsewhere. The page limit for regular papers is 13 pages in Springer Verlag LNCS style. Surveys and tutorials maybe longer. Use the WRS06 submission page, handled by the EasyChair conference system, to submit abstracts, papers and to update a previous submission.
Publication
Informal proceedings of accepted contributions will be available on-line. A hard copy will be distributed at the workshop to registered participants. Authors of selected contributions will be invited to submit a revised version, after the workshop, for inclusion in a collection. We anticipate the publication of formal proceedings in the Elsevier ENTCS series.
