Code cloning is a controversial software engineering practice due to contradictory claims regarding its impacts on software evolution and maintenance. While a number of studies identify some positive aspects of code clones, there is strong empirical evidence of some negative impacts of clones too. Focusing on the issues related to clones researchers suggest to manage code clones through detection,...
Code clones are identical or similar code fragments in a code base. A group of code fragments that are similar to one another forms a clone class. Clone fragments from the same clone class often need to be changed together consistently and thus, they exhibit evolutionary coupling. Evolutionary coupling among clone fragments within a clone class has already been investigated and reported. However,...
