WPTE 2020

7th International Workshop on Rewriting Techniques for Program Transformations and Evaluation


FSCD - IJCAR and associated workshops will be held as Virtual Conferences. To have an event where participants are not only there to enjoy the talks, but also to have informal interactions with each others, a common platform to handle all virtual workshops together will be used, so that all participants will be in the same virtual space.

WPTE 2020 is part of "Paris Nord Summer of LoVe 2020", a joint event on LOgic and VErification at Université Paris 13, made of Petri Nets 2020, IJCAR 2020, FSCD 2020, and over 20 satellite events. More information here

About WPTE

The aim of WPTE is to bring together the researchers working on program transformations, evaluation, and operationally based programming language semantics, using rewriting methods, in order to share the techniques and recent developments and to exchange ideas to encourage further activation of research in this area.

Paper Selection and Proceedings

Contributions to WPTE 2020

For the paper submission deadline an extended abstract of at most 10 pages is required to be submitted. The extended abstract may present original work or also work in progress. Based on the submissions the program committee will select the presentations for the workshop. All selected contributions will be included in the informal proceedings distributed to the workshop participants. One author of each accepted extended abstract is expected to present it at the workshop. Submissions must be prepared in LaTeX using the EPTCS macro package (http://style.eptcs.org/). Extended abstract submission to WPTE 2020 is handled by easychair at https://easychair.org/conferences/?conf=wpte2020.

Formal Proceedings

WPTE post-proceedings of selected papers will be published in a JLAMP special issue. For this, full papers must be submitted until the post-proceedings deadline. The authors of all presented contributions will have the opportunity (but no obligation) to submit a full paper for the formal post-proceedings. These must represent original work and should not be submitted to another conference at the same time. The submission deadline for these post-proceedings will be after the workshop in September 2020. There will be a second round of reviewing for selecting papers to be published in the formal proceedings.
