A hierarchical method for detecting codeclone

To improve the efficiency of the software system, the classifiers goes through the process of fine tuning on code clone detection. As code clone affects the software as a major factor in maintenance. This can be accomplished by finding simple clones. Once these simple codes have been fine tuned it can be detected. Because when the size of the simple clones increases in software, the execution time naturally increases. Detecting such clones can help in understanding design of the system for better maintenance and in reengineering for reuse.
