The GTOPX dataset is an extended version of the GTOP database maintained by the European Space Agency (ESA), focusing on global trajectory optimization problems. This dataset includes 10 independent benchmark instances, each representing a realistic interplanetary trajectory design problem with mixed-integer and multi-objective characteristics. The GTOPX dataset was created to provide researchers with a platform for testing advanced (meta-)heuristic and hybrid optimization algorithms. The dataset covers various trajectory design problems such as Cassini1, Cassini2, etc., each with its specific objectives and constraints. The development process of the GTOPX dataset involves selecting problems from the original GTOP database and adding new problem instances to enhance the dataset's diversity and challenging nature. The application scenarios of the GTOPX dataset mainly focus on aerospace engineering and optimization algorithm research, aiming to solve complex trajectory optimization problems and promote the development of related technologies.
