        Second International Workshop on Reduction Strategies 
               in Rewriting and Programming (WRS 2002)

               http://www.dsic.upv.es/users/elp/WRS2002
               
                 held in conjunction with RTA 2002
                 Copenhagen, Denmark, July 21, 2002

--------------------------------------------------------------------------

BACKGROUND AND AIMS

Reduction strategies in rewriting and programming have attracted an
increasing attention within the last years. New types of reduction
strategies have been invented and investigated, and new results on
rewriting / computation under particular strategies have
been obtained. Research in this field ranges from primarily theoretical
questions about reduction strategies to very practical application and
implementation issues. The need for a deeper understanding of reduction
strategies in rewriting and programming, both in theory and practice,
is obvious, since they bridge the gap between unrestricted general
rewriting (computation) and (more deterministic) rewriting with
particular strategies (programming). Moreover, reduction strategies
provide a natural way to go from operational principles (e.g., graph
and term rewriting, narrowing, lambda-calculus) and semantics (e.g.,
normalization, computation of values, infinitary normalization,
head-normalization) to implementations of programming languages. 

Therefore any progress in this area is likely to be of interest not
only to the rewriting community, but also to neighbouring fields like
functional programming, functional-logic programming, and termination
proofs of algorithms.  

The workshop wants to provide a forum for the presentation and
discussion of new ideas and results, recent developments, new research
directions, as well as of surveys on existing knowledge in this
area. Furthermore we aim at fostering interaction and exchange between
researchers and students actively working on such topics. 
The workshop will be held in conjunction with RTA 2002 in Copenhagen 
(Denmark) on July 21, 2002. 

The workshop is (co-)organized by TU Valencia and TU Wien.


TOPICS OF INTEREST

Topics of interest include, but are not restricted to,  
- theoretical foundations for the definition and semantic description 
  of reduction strategies
- strategies in different frameworks (term rewriting, graph rewriting,
  infinitary rewriting, lambda calculi, higher order rewriting and 
  explicit substitutions, conditional rewriting, rewriting with 
  built-ins, narrowing, constraint solving, etc.) and their application 
  in (equational, functional, functional-logic) programming (languages)
- properties of reduction strategies / computations under
  strategies (e.g., completeness, computability, decidability,
  complexity, optimality, (hyper-)normalization, cofinality,
  fairness, perpetuality, context-freeness, neededness, laziness,
  eagerness, strictness)
- interrelations, combinations and applications of
  reduction under different strategies (e.g., equivalence
  conditions for fundamental properties like termination and
  confluence, applications in modularity analysis, connections
  between strategies of different frameworks, etc.)
- program analysis and other semantics-based optimization techniques
  dealing with reduction strategies
- rewrite systems / tools / implementations with flexible /
  programmable strategies as essential concept / ingredient
- specification of reduction strategies in (real) languages
- data structures and implementation techniques for reduction
  strategies.


SUBMISSIONS

We solicit papers on all aspects of reduction strategies in
rewriting and programming. Submissions should describe unpublished
work, except for survey papers which are explicitly welcome,
too. Submissions should not exceed 10 pages (however, survey papers
may be longer) and be sent in postscript format to the PC co-chairs
to the following e-mail address:

  [email protected] 
   
before April 15, 2002. Submissions should include the title, authors'
names,  affiliations, addresses, and e-mail. Selection of papers by 
the PC will be based on originality, significance, and correctness. 
Accepted papers will be included in the workshop proceedings that 
will be available at the workshop, and electronically on the web.
Final versions will be due by June 17, 2002. 


PUBLICATION

Accepted papers will be included in the workshop proceedings that 
will be available at the workshop, and electronically on the web. 
A special issue of the Journal of Symbolic Computation on

   Reduction Strategies in Rewriting and Programming

will be designated for revised and extended versions of selected 
contributions from both WRS 2001 (Utrecht, May 2001) and WRS 2002.
