All the data created for the publication "A General Approach of Automated Environment Design for Learning the Optimal Power Flow" by Wolgast and Nieße. The dataset contains all training runs performed, meta-data about the training run, and various metrics during the course of training and environment design optimization, which were used to generate the results and plots. The source code to re-produce the plots for the publication (and everything else) can be found on GitHub: https://github.com/Digitalized-Energy-Systems/auto-env-design
