Survey of research on code clone technique

Detection and management of clone codes in software system is one of the fundamental questions in software engineering, is widely used in many fields, such as software quality, maintenance, architecture, evolution, patent, plagiarism, and so on. This paper introduced the processes and technologies of clone detection and analyzed their strengths and weaknesses. And it also introduced the related works of the clone evolution, some techniques of the clone management and especially presented the techniques for refactoring of clones. At last, it summarized the achievement of the research and discussed the challenging problems of the research on code clone.
