The WRS workshop promotes research and collaboration in the area of reduction strategies in rewriting and programming. It encourages the presentation of new directions, developments, and results as well as surveys and tutorials on existing knowledge in this area. Reduction strategies define which (sub)expression(s) should be selected for evaluation and which rule(s) should be applied. These choices affect fundamental properties of computations such as laziness, strictness, completeness, and efficiency, to name a few. For this reason programming languages such as Elan, Maude, OBJ, Stratego, and TOM allow the explicit definition of the evaluation strategy, whereas languages such as Clean, Curry, and Haskell allow its modification. In addition to strategies in rewriting and programming, WRS also covers the use of strategies and tactics in other areas such as theorem and termination proving.

Previous editions of the workshop were held in Utrecht (2001), Copenhagen (2002), Valencia (2003), Aachen (2004), Nara (2005), Seattle (2006), Paris (2007), Hagenberg (2008), Brasilia (2009), Edinburgh (2010), Novi Sad (2011), and Manchester (2012); the 2010 and 2012 editions were joint with the STRATEGIES workshop. Further information can be found at the permanent site for WRS.

WRS 2013 will be co-located with RTA 2013 (24th International Conference on Rewriting Techniques and Applications), as a satellite event of RDP, the Federated Conference on Rewriting, Deduction, and Programming. WRS 2013 will be held on 27 June in Eindhoven, the Netherlands.
The submission process is in two stages.
  1. Before the workshop, authors are invited to submit an extended abstract (max. 5 pages) to be formatted in the EasyChair class style through the EasyChair submission site:


    Accepted abstracts will be presented at the workshop and included in the preliminary proceedings, available at the workshop.

  2. After the workshop, authors will be invited to submit a full paper of their presentation (typically a 15-pages paper), which will be refereed and considered for publication in an electronic journal, such as Electronic Proceedings in Theoretical Computer Science.
Beyond original ideas and recent results not published nor submitted elsewhere, we also invite authors to submit a 5-pages abstract describing relevant work that has been or will be published elsewhere, or work in progress. These submissions will be only considered for presentation at the workshop and inclusion in the preliminary proceedings but not in the final proceedings.
