The workshop focuses on Search-Based Model Engineering (SBME), which aims to bring together ideas from software engineering (in particular model-driven engineering (MDE), which is about enabling the development of software from high-level representations called models) and optimisation (primarily, but not limited to, evolutionary and search-based methods) to simplify the specification and solving of optimisation problems in a range of domains. The goal of the workshop is to identify new research challenges and opportunities, in particular for research jointly between software-engineering researchers and researchers from mathematical optimisation and from particular domains (such as bioinformatics, computational biology, geography and robotics).
