Software engineering is a wider area of research. Various hot topics are picked for research like quality prediction, bug detection, clone detection, efforts estimation etc. Software clone detection can save the development efforts and helpful in developing efficient software. The clones are useful for code reuse but, the copy-paste technical may increase the problem of code reliability and robustness. Unnecessary duplicate code not only affects the software itself but entire system performance is affected. So, this research covers the software clone detection techniques. The scientists have introduced various tools and techniques for clone detection such as token based code representation, abstract syntax tree based model, CDLH, NiCad, LWH model, PMD, CodePro etc. In this paper, various researches are studied and compared.

Abstract Syntax Tree, Code Clones, CCLearner, NiCad, SDLC.
