About

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.

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 an extended abstract of at most 10 pages is required. The extended abstract may present original work, but also work in progress. 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 extended abstract is expected to present it at the workshop, either in-person or remotely (although we strongly encourage in-person participation). Submissions must be prepared in LaTeX using the EPTCS macro package.

All submissions will be electronic via https://easychair.org/conferences/?conf=wpte2023.
