Abstract Automated Program Repair (APR) has attracted significant attention from software
engineering research and practice communities in the last decade. Several teams have …

We revisit the performance of template-based APR to build comprehensive knowledge
about the effectiveness of fix patterns, and to highlight the importance of complementary …

Most fault localization techniques take as input a faulty program, and produce as output a
ranked list of suspicious code locations at which the program may be defective. When …

Automated program repair (APR) has great potential to reduce bug-fixing effort and many
approaches have been proposed in recent years. APRs are often treated as a search …

We propose Nopol, an approach to automatic repair of buggy conditional statements (ie, if-
then-else statements). This approach takes a buggy program as well as a test suite as input …

Despite being one of the most basic tasks in software development, debugging is still
performed in a mostly manual way, leading to high cost and low performance. To address …

Software engineering practitioners often spend significant amount of time and effort to
debug. To help practitioners perform this crucial task, hundreds of papers have proposed …

Fault Localization (FL), in which a developer seeks to identify which part of the code is
malfunctioning and needs to be fixed, is a recurring challenge in debugging. To reduce …

Fix pattern-based patch generation is a promising direction in Automated Program Repair
(APR). Notably, it has been demonstrated to produce more acceptable and correct patches …

Test-based automated program repair (APR) has attracted huge attention from both industry
and academia. Despite the significant progress made in recent studies, the overfitting …
