Clones are generally considered bad programming practice in software engineering
folklore. They are identified as a bad smell (Fowler et al. 1999) and a major contributor to …

Code Clones-duplicated source fragments-are said to increase maintenance effort and to
facilitate problems caused by inconsistent changes to identical parts. While this is certainly …

Code duplication is a well‐documented problem in industrial software systems. There has
been considerable research into techniques for detecting duplication in software, and there …

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 …

To study the impact of code clones on software quality, researchers typically carry out their
studies based on fine-grained analysis of inconsistent changes at the revision level. As a …

It has been broadly assumed that code clones are inherently bad and that eliminating clones
by refactoring would solve the problems of code clones. To investigate the validity of this …

Studies show that programs contain much similar code, commonly known as clones. One of
the main reasons for introducing clones is programmers' tendency to copy and paste code to …

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 …

Code clone genealogies show how clone groups evolve with the evolution of the associated
software system, and thus could provide important insights on the maintenance implications …

Code clones are said to threaten the maintainability of a system--especially when the system
evolves and source code is changed. Whether clones truly increase maintenance effort can …
