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

If you have a solution for a challenge from the list above, please submit it through EasyChair ( – Challenge Solutions). Solutions have a maximum of 4 pages including all text, figures etc + 1 additional page containing only references may be included. Accepted papers will be presented during the conference. At least one author of each accepted solution must register for the conference. Submissions must follow the ACM Master Article Template:

Latex users are indicated to 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:

\acmConference[SPLC'22]{26th ACM International Systems and Software Product Line Conference}{12--16 September, 2022}{Graz, Austria}
