Görg, Torsten2023-03-132023-03-132015https://dl.gi.de/handle/20.500.12116/40811This paper provides several ideas how to improve the performance of PDG-based code clone detection techniques. We suggest an efficient way to handle the subgraph isomorphism problem without losing precision and present an algorithm that avoids the unnecessary matching effort for subclones of larger clones.enText/Journal Article0720-8928
