International Conference on Software and Systems Reuse, Product Lines, and Configuration (VARIABILITY 2026): Last Call for Doctoral Symposium Papers
George Angelos Papadopoulos
*** Last Call for Doctoral Symposium Papers ***
International Conference on Software and Systems Reuse, Product Lines,
and Configuration (VARIABILITY 2026)
29 September - 2 October 2026, 5* St. Raphael Resort and Marina
Limassol, Cyprus
https://conf.researchr.org/home/variability-2026
VARIABILITY is a new conference that has been merged of three prominent conferences
focussing on software and systems variability, configuration and reuse: SPLC (the
International Systems and Software Product Line Conference, 29 successful editions,
ranked as a top conference), VaMoS (the International Working Conference on Variability
Modelling of Software-Intensive Systems, 19 successful editions), and ICSR (the
International Conference on Systems and Software Reuse, 22 successful editions).
The Doctoral Symposium of VARIABILITY 2026 aims to provide a supportive environment
that enables doctoral students to get constructive feedback on their research. Students
will discuss their work with experienced community members and other students. The
event is open to any PhD student whose research topic concerns software variability,
software and systems reuse, product lines, and configuration. This includes PhD students
at early stages of their research (after setting up a research program, but before having
results). Accordingly, we will have two submission categories:
• Late – late-stage PhD students, having at least 6 months of work after the conference
and before their expected completion; and
• Early – early-stage PhD students, with at least 6 months of work already performed
prior to the submission date.
Submissions/Publishing
Requirements
To participate, students should prepare a research plan answering the following questions:
• The research problem being addressed and its importance
• The research methodology and techniques being applied
• The solution being proposed, its novelty and validity
• The relation of the work with the state-of-the-art
• Preliminary results and their impact (for the ‘late’ category)
The research plan aims to provide clear material that can be used as a basis for guidance
and discussion. It is strongly recommended that students discuss the research plan with
their supervisors. The following structure is recommended:
• Front matter: Title, your name, email address, abstract
• Introduction and Motivation: Introduction, description of the problem tackled and its
importance; what the literature says about this problem and where existing work fails; how
you plan to tackle this problem; what results you envision; how you plan to validate your
solution.
• Research Questions: Clearly state the research questions you plan to address and any
assumptions you make.
• Research Methodology and Approach: The research methodology you plan to use (e.g.,
design science, action research), including the techniques you plan to use (e.g.,
formalisation, algorithm specification, case studies). In line with your research
methodology, describe your research approach: what novel methods and/or technology
you are going to build, how you are going to do that, including aspects such as data
collection, software prototyping and evaluation. Discuss any threats to validity you can
envision and expect to address (to the extent possible).
• Preliminary Results (for the ‘late’ category): Overview of the results you achieved so far.
Provide an example to explain how the solution obtained so far works. This is only
applicable to the ‘late’ category.
• Work plan: Both categories of submissions should consider an overall work plan for the
whole thesis. Submissions for the ‘late’ category can mention which parts of the work plan
they have reached so far. Both categories of submissions should consider the schedule for
the next 12 months.
Submission Format
VARIABILITY DS papers will be published in the second volume of the VARIABILITY
conference proceedings published by Springer (Lecture Notes in Computer Science).
Submissions should be in the Springer format (please see the information about the format
in the call for the research track). All submissions must be in English, in PDF format, and
neither contain proprietary or confidential material. The page limits for doctoral
symposium submissions are as follows:
• Early category: 6 pages (+2 pages for references only)
• Late category: 8 pages (+2 pages for references only)
Submissions should be sent as a single file via Easychair track Doctoral Symposium:
https://easychair.org/my/conference?conf=variability2026 (please select ‘VARIABILITY
2026 – Doctoral Symposium Track’).
Evaluation
At least two reviewers will evaluate each submission according to the research’s relevance,
originality and feasibility. VARIABILITY DS papers will be published in the second volume of
the VARIABILITY conference proceedings published by Springer. The PhD student of the
accepted submission must register and attend VARIABILITY 2026 so that the submission
can be published.
Format of the Symposium
The symposium will be held in conjunction with VARIABILITY 2026. In addition to
presentations by PhD students and discussions, the doctoral symposium will feature a
keynote/panel and ask-me-anything sessions with experienced researchers. All students
are expected to attend every symposium session.
