Copy and paste activities create clone groups in software systems. The evolution of a clone
group across the history of a software system is termed as clone genealogy. During the …

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 …

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 …

If two fragments of source code are identical or similar to each other, they are called code
clones. Code clones introduce difficulties in software maintenance and cause bug …

Cloning in software systems is known to create problems during software maintenance.
Several techniques have been proposed to detect the same or similar code fragments in …

Excessive code duplication is a bane of modern software development. Several
experimental studies show that on average 15 percent of a software system can contain …

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 …

Despite a decade of active research, there has been a marked lack in clone detection
techniques that scale to large repositories for detecting near-miss clones. In this paper, we …

Recent research describes how code clones in source code decrease reliability of the
program and require more development cost. To solve the problem, several code clone …

Code clones, ie instances of duplicated code, can be found in many software systems. They
adversely affect the software systems’ quality, in particular their maintainability and …
