Bad smells are sub-optimal code structures that may represent problems needing attention.
We conduct an extensive literature review on bad smells relying on a large body of …

Code clone detection is an important problem for software maintenance and evolution. Many
approaches consider either structure or identifiers, but none of the existing detection …

At the heart of software evolution is a sequence of edit actions, called an edit script, made to
a source code file. Since software systems are stored version by version, the edit script has …

Copying code and then pasting with large number of edits is a common activity in software
development, and the pasted code is a kind of complicated Type-3 clone. Due to large …

To keep pace with the increasing demand for custom-tailored software systems, companies
often apply a practice called clone-and-own, whereby a new variant of a software system is …

Duplicated code or code clones are a kind of code smell that have both positive and
negative impacts on the development and maintenance of software systems. Software clone …

Clone detection finds application in many software engineering activities such as
comprehension and refactoring. However, the confounding configuration choice problem …

In this paper, we present a large-scale study of repetitiveness of code changes in software
evolution. We collected a large data set of 2,841 Java projects, with 1.7 billion source lines …

Fast changing hardware and software technologies in addition to larger and more
specialized customer bases demand software tailored to meet very diverse requirements …

The presence of duplicated code in software systems is significant and several studies have
shown that clones can be potentially harmful with respect to the maintainability and …
