The Ninth International Workshop on Verification and Program Transformation (VPT 2021) aims to bring together researchers working in the areas of Program Verification and Program Transformation.

The workshop will be held fully online mode by ETAPS decision, and remote participation and lectures and talks delivery will be possible.

The previous workshops in this series were:

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.

Topics of interest include, but are not limited to:

Important Dates

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 (, via the Easychair submission website for VPT 2021 : .

Regular papers must describe original work that has not been published, or currently 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 Also papers that already appeared in unpublished or informally published workshop proceedings may be submitted.

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.


We hope to publish the post-proceedings in the Electronic Proceedings in Theoretical Computer (EPTCS) series (, as was done for previous editions of VPT.

If the workshop will attract 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 editions of the workshop.
