“…However, they are generally designed with a different purpose: finding similar intra-model (and to a lesser extent inter-model) fragments generated by a legitimate copy and paste reuse. Approaches for model clone detection have been proposed on UML models (Störrle, 2015), graphs (Pham, Nguyen, Nguyen, Al-Kofahi, & Nguyen, 2009), Simulink models (Deissenboeck, Hummel, Juergens, Pfaehler, & Schaetz, 2010) or rule-based model transformations (Strüber, Acret ¸oaie, & Plöger, 2017) while other proposals target general model comparison (Brun & Pierantonio, 2008), model alignment (Falleri, Huchard, Lafourcade, & Nebut, 2008;Kolovos, 2009) or model versioning (Constant, 2012). In theory, all these works could be systematically executed on all combinations of models in a repository to find suspicious pairs of models but in practice this is not really feasible.…”
