Feature modeling is widely used to systematically model features of variant-rich software
systems and their dependencies. By translating feature models into propositional formulas …

Diff tools are essential in developers' daily workflows and software engineering research.
Motivated by limitations of traditional line-based differencing, countless specialized diff tools …

Variability permeates software development to satisfy ever-changing requirements and
mass-customization needs. A prime example is the Linux kernel, which employs the C …

Software systems are subject to frequent changes, for example to fix bugs or meet new
customer requirements. In variational software systems, developers are confronted with the …

Tracing features to software artifacts is a crucial yet challenging activity for developers of
variability-intensive software projects. Developers can provide feature traces either …

Software is subject to changes and revisions during its development life cycle. For
configurable software systems, changes may be made to functionality of source code as well …

Clone-and-own development is a simple and flexible approach to realize multi-variant
software systems in practice but typically provokes costly challenges in maintaining a …

Changes to the artifacts, such as source code, of software product lines often affect a
multitude of variants. Variation diffs are a complete model for describing and analyzing …

Version control systems such as Git and Subversion are widely used. Even though software
often has to allow for variability, the commonly used version control systems do not provide …

Developing variant-rich systems utilizing methods from software product-line engineering
(SPLE) has become favored, as it offers strategies for systematic reuse of implementation …
