RRRR 2023

The Second Workshop on Reproducibility and Replication of Research Results (RRRR 2023) is part of ETAPS 2023 in Paris, France. It provides a forum to present novel approaches to foster reproducibility of research results, and replication studies of existing work, in the broad area of formal methods research. Its goal is to spread the word on best practices, and reward the work invested in replicating results.

Where reproducible research can be independently confirmed by third parties using artifacts provided by the original authors, replicating a result means to independently obtain it using new measurements, data, or implementations. RRRR will improve the knowledge transfer between the many separate initiatives – like artifact evaluations and tool competitions – that today support reproducibility, and provide a venue to formally publish replication studies, recognising their immense benefit to the scientific community and the hard work involved.


RRRR 2022 takes place on Saturday, April 22, 2023, as part of the ETAPS workshops at Institut Henri Poincaré in Paris, France. The programme for the day is as follows:

10:00-10:30 Coffee break

RRRR invited submissions in two topics and two formats. All accepted submissions are collected informally as PDFs in the programme above. Submissions were handled via EasyChair.


Submissions were encouraged in, but not limited to, two main topics:

Submissions should be related to research in the broad area of formal methods that would be in scope for one of the ETAPS conferences in principle. It is not required that the earlier work that a replication study is based on has been published at ETAPS.

Submission Types

RRRR accepted two types of submissions:

The page limits are to be interpreted as guidelines, not as absolute limits. Short papers and presentation abstracts are reviewed by the organisers. We encouraged short papers to be accompanied by an artifact for reproduction. Authors of all accepted submissions present their work at the workshop. We encourage demonstrations to be integrated in presentations, in particular for replication studies.

Special Issue in STTT

Authors of accepted papers and abstracts will be invited to submit an extended/full version of their work to a special issue in the International Journal on Software Tools for Technology Transfer (STTT). Where applicable, we expect these journal submissions to be accompanied by an artifact for reproduction that will be permanently archived with a DOI upon publication. All journal submissions will undergo a full reviewing process.


All dates are in 2023 and all deadlines are "anywhere on Earth" (UTC-12). The organisers appreciated an early informal indication, via , of the intention to submit to RRRR 2023.
