[Caml-list] WPTE 2026: Call for Papers

[Carsten Fuhs]

WPTE 2026 (affiliated with FLoC 2026 and FSCD 2026 in Lisbon, Portugal)

12th International Workshop on Rewriting Techniques for Program
Transformations and Evaluation (19 July 2026)

Webpage:     https://wpte2026.github.io/
Submission:  https://submissions.floc26.org/wpte/
Deadline:    22 April 2026

---------------------------------------------------------------------------
The aim of WPTE is to bring together 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.

Topics of Interest
---------------------------------------------------------------------------
* Correctness of program transformations, optimizations and translations.
* Program transformations for proving termination, confluence, and
   other properties.
* Correctness of evaluation strategies.
* Operational semantics of programs, operationally-based program
   equivalences such as contextual equivalences and bisimulations.
* Cost-models for arguing about the optimizing power of transformations
   and the costs of evaluation.
* Program transformations for verification and theorem proving purposes.
* Translation, simulation, equivalence of programs with different
   formalisms, and evaluation strategies.
* Program transformations for applying rewriting techniques to programs
   in specific programming languages.
* Program transformations for program inversions and program synthesis.
* Program transformation and evaluation for Haskell and rewriting.
* Rewriting-based transformations for bidirectional programming and
   reversible computation.

Submission Guidelines
---------------------------------------------------------------------------
For the paper submission deadline, a regular paper or extended abstract
of at most 10 pages is required. WPTE 2026 accepts submissions in three
categories:

* Regular paper, reporting on completed work that has not yet been
   formally published and is not under submission for formal publication
   at another venue (journal, conference, workshop with formal
   proceedings).

* Work-in-progress extended abstract, reporting on work in progress.

* Presentation-only extended abstract, a short version of a paper
   currently submitted to or formally published at another venue.

The program committee will select the presentations for the workshop
based on the submissions. All selected contributions will be included in
the informal proceedings distributed to the workshop participants. One
author of each accepted contribution is expected to present it at the
workshop in person.

Submissions must be prepared in LaTeX using the EPTCS macro package.

All submissions are to be made via:

   https://submissions.floc26.org/wpte/

Post-Proceedings or Journal Special Issue
---------------------------------------------------------------------------
For the 2020-2025 editions, papers from WPTE were selected for
post-submission and eventual publication in JLAMP special issues.
We will discuss, also based on interest expressed by authors at the
workshop, whether to arrange a special issue or other formal proceedings
for regular papers and completed work-in-progress extended abstracts
selected from this year's edition.

Important Dates
---------------------------------------------------------------------------
Submission of regular papers and extended abstracts: 22 April 2026 (AoE)
Notification of acceptance: 25 May 2026
Early Registration for the workshop: 1 June 2026
Final version for informal proceedings: 29 June 2026
Workshop: 19 July 2026
Submission to post-proceedings/special issue: autumn 2026 (tbd)
