Modern computer systems are highly-configurable, complicating the testing and debugging
process. The sheer size of the configuration space makes the quality of software even …

Performance bugs are often hard to detect due to their non fail-stop symptoms. Existing
debugging techniques can only detect performance bugs with known patterns (eg, inefficient …

Software projects embrace variability to increase adaptability and to lower cost; however,
others blame variability for increasing complexity and making reasoning about programs …

Variability-sensitive verification pursues effective analysis of the exponentially many variants
of a program family. Several variability-aware techniques have been proposed, but …

Background: Performance bugs can lead to severe issues regarding computation efficiency,
power consumption, and user experience. Locating these bugs is a difficult task because …

Software performance is critical for how users perceive the quality of software products.
Performance bugs-programming errors that cause significant performance degradation-lead …

Software performance is important for ensuring the quality of software products.
Performance bugs, defined as programming errors that cause significant performance …

Software performance is one of the important qualities that makes software stand out in a
competitive market. However, in earlier work we found that performance bugs take more …

A good understanding of the impact of different types of bugs on various project aspects is
essential to improve software quality research and practice. For instance, we would expect …

Developers frequently use inefficient code sequences that could be fixed by simple patches.
These inefficient code sequences can cause significant performance degradation and …
