Code and data for ECAI24

Code and data for the ECAI24 paper Nesig: A neuro-symbolic method for learning to generate planning problems.
Experiment results can be found in experiments (for NeSIG and ablations) and in data/instance_generators for ad-hoc generators.
Each subfolder experiments/<experiment_id> contains a file experiment_info.json with the parameters used to run the experiment.
NeSIG logs and checkpoints are not provided due to their large size.
