Each of these cases presents a set of concrete tasks (some of which may be optional) which are to be solved by the participants. The case descriptions, which typically include pointers to additional resources, are available through the respective links above.

The SPLC Challenge Track now seeks your solutions to all of these interesting problems of various natures. To participate, select a case you are interested in and submit a paper that tackles the tasks and challenges described in that challenge case. You are welcome to submit multiple papers, where each paper is related to one case. Papers should be accompanied by solution artefacts as necessary, depending on the case study and the concrete tasks which are to be solved. Thus, solution artefacts may range from hand-crafted sketches or models to fully automatically generated development artefacts or analysis results. Wherever possible, solution artefacts should be made available in a public repository or be hosted on a publicly available website to ensure the reproducibility of the results. The paper should include a description of your solution and include an evaluation according to the evaluation criteria stated by the respective case description. Note that early ideas, early results, and partial solutions are welcome. Also, note that submissions that apply existing tools and techniques to address a given challenge are also welcome.

Solutions will be evaluated by program committees, one separate committee per case, which are comprised of reviewers who have the expertise required to evaluate submitted solutions. Typically, one or two case authors are part of a case’s PC. Accepted solutions will be presented and discussed at the conference and their corresponding papers will be published in the official conference proceedings. Please note that case authors cannot submit a solution to their own challenge.

Submission Information

Solutions have a maximum of 6 pages including all text, figures, etc, plus 1 additional page containing only references may be included.

Submissions must adhere to the latest ACM Master Article Template:

Latex users should use the “sigconf” option, so they are recommended to use the template that can be found in “sample-sigconf.tex”. In this way, the following latex code can be placed at the start of the latex document to create a double column layout:

\acmConference[SPLC'23]{27th International Systems and Software Product Line Conference}{August 28--September 1, 2023}{Tokyo, Japan}

The SPLC proceedings will be published in the ACM Digital Library.

By submitting your article to an ACM Publication, you are hereby acknowledging that you and your co-authors are subject to all ACM Publications Policies, including ACM’s new Publications Policy on Research Involving Human Participants and Subjects. Alleged violations of this policy or any ACM Publications Policy will be investigated by ACM and may result in a full retraction of your paper, in addition to other potential penalties, as per ACM Publications Policy.

Please ensure that you and your co-authors obtain an ORCID ID, so you can complete the publishing process for your accepted paper. ACM has been involved in ORCID from the start and we have recently made a commitment to collect ORCID IDs from all of our published authors. The collection process has started and will roll out as a requirement throughout 2022. We are committed to improve author discoverability, ensure proper attribution and contribute to ongoing community efforts around name normalization; your ORCID ID will help in these efforts.

The author of the accepted submission must pay a full registration fee for the submission to be published. SPLC 2023 is primarily a physical event and papers are expected to be presented on site, except where no co-author is able to attend SPLC 2023 in Tokyo. If any co-author of a paper is attending physically, they will need to present the paper. If no co-author is able to come to Tokyo to present an accepted paper, we ask that you let us know for which paper no co-author is able to present in-person. Such remote presenters will be accommodated for presenting online, live where feasible or else via a recording in exceptional circumstances.
