In the combination of Model-Driven Engineering (MDE) and Search-Based Software Engineering (SBSE), genetic operations are one of the key ingredients. Our work proposes a novel adaptation of automatic query reformulations as genetic operations that leverage the latent semantics of software models (the cornerstone artefact of MDE). an open-source implementation of the baselines (single-point crossover and random mutation) and variants of our reformulation-based genetic operations are available here:
