Clone Evolution Visualization System for Software Maintenance at Osaka University
Explore the CCEvovis system, a tool designed by researchers at Osaka University for visualizing the evolution of code clones to support software maintenance. The system includes features like Clone Notifier and a proposed tool for visualizing clone evolution using stacked bar graphs. Discover how this system aids in code clone management and refactoring processes.
