Research >> Managing Duplication in Source Code
Copy-and-Paste is a common practice of reusing code when developing software. This ad hoc form of code reuse may introduce multiple identical code blocks, called code clones, which make future modifications to a software system difficult. For instance, a developer fixing a bug in a section of code may be unaware of the existence of other cloned blocks in the system with a similar defect. The goal of this project was to investigate techniques, and to propose new tools that would assist developers become aware of code clones when modifying the source code of a system. We received an ACM SIGSOFT Distinguished Paper Award for the contributions of this project. Our contributions are summarized in the papers below.
