CONTEXT: Reusing software by means of copy and paste is a frequent activity in software
development. The duplicated code is known as a software clone and the activity is known as …

This report summarizes my overview talk on software clone detection research. It first
discusses the notion of software redundancy, cloning, duplication, and similarity. Then, it …

Clone detection of source code is among the most fundamental software engineering
techniques. Despite intensive research in the past decade, existing techniques are still …

We provide an extensive overview of existing research in the field of software refactoring.
This research is compared and discussed based on a number of different criteria: the …

Code duplication or copying a code fragment and then reuse by pasting with or without any
modifications is a well known code smell in software maintenance. Several studies show …

Many companies develop software product lines-collections of similar products-by cloning
and adapting artifacts of existing product variants. Transforming such cloned product …

Literature on the topic of code cloning often asserts that duplicating code within a software
system is a bad practice, that it causes harm to the system's design and should be avoided …

The ability to evolve software rapidly and reliably is a major challenge for software
engineering. In this introductory chapter we start with a historic overview of the research …

Although programmers frequently copy and paste code when they develop software,
implications of common copy and paste (C&P) usage patterns have not been studied …

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 …
