The aim of the workshop is to bring together researchers working in the fields of Program Verification and Program Transformation.

There is a great potential for beneficial interactions between these two fields because:

* On one hand, methods and tools developed in the field of Program Transformation such as partial evaluation, fold/unfold transformations, and supercompilation, have all been applied with success for the verification of infinite state and parameterized systems.

* On the other hand, model checking, abstract interpretation, SAT and SMT solving and automated theorem proving have been used to enhance program transformation techniques. Moreover, the formal certification of program transformation tools, such as automated refactoring tools and compilers, has recently attracted considerable interest, posed major challenges.

The workshop will provide a forum where researchers from these fields may interact and foster new developments.

The workshop solicits research, position, application, and system description papers with a special emphasis on case studies, demonstrating viability of the interactions between the research fields of program transformation and program verification in a broad sense. Also papers in related areas, such as program testing and program synthesis are welcomed.

The workshop offers twofold benefits for the verification community. On the one hand it will rise awareness of and stimulate the development of novel verification methods and techniques. On the other hand it will draw attention of the community to the novel and challenging verification problems and research opportunities.

Submission Guidelines

Authors should submit an electronic copy of the regular paper in PDF, formatted in the Electronic Proceedings in Theoretical Computer Science LaTeX Style (http://style.eptcs.org/), via the Easychair submission website for VPT 2022 ( https://easychair.org/conferences/?conf=vpt2022 ) by 17th February. Page numbers (and, if possible, line numbers) should appear on the manuscript to help the reviewers in writing their report. So, for LaTeX, we recommend that authors use:
\pagestyle{plain}
\usepackage{lineno}
\linenumbers

Papers must describe original work that has not been published, nor is presently submitted, to a journal, conference, or workshop with refereed proceedings. Also papers that already appeared in unpublished or informally published workshop proceedings may be submitted (please contact the PC co-chairs in case of questions).

Each submission must include on its first page the paper title; authors and their affiliations; contact author's email; abstract; and three to four keywords that will be used to assist the PC in selecting appropriate reviewers for the paper. Page numbers should appear on the manuscript to help the reviewers in writing their report.

Regular paper submissions should not exceed 15 pages including references but excluding well-marked appendices not intended for publication. Reviewers are not required to read the appendices, and thus papers should be intelligible without them.

Proceedings

Revised versions of all the accepted regular papers and accepted extended abstracts, taking into account the feedback received at the workshop, will be published in a volume of the Electronic Proceedings in Theoretical Computer (EPTCS) series after the workshop.

If the workshop attracts sufficiently many high quality papers, a special issue of a journal on the topic of the workshop will be considered. The special issue will be open to high quality papers accepted for presentation in previous/past editions of the workshop.
