Pseudocode Yes Algorithm 1 OK Search
Open Source Code Yes The code is available at https://github.com/IBM/kstar.
Open Datasets Yes The benchmark set consists of all benchmarks from optimal tracks of International Planning Competitions 1998-2018, a total of 1827 tasks in 65 domains.
Dataset Splits No The paper mentions using benchmarks from International Planning Competitions, but it does not specify any dataset split information (percentages, sample counts, or detailed splitting methodology) for training, validation, or testing.
Hardware Specification Yes All experiments were performed on Intel(R) Xeon(R) Gold 6248 CPU @ 2.50GHz machines, with the timeout of 30 minutes and memory limit of 8GB per run.
Software Dependencies No The paper mentions using the 'Fast Downward planning system' and various heuristics (LMcut, M&S, CEGAR, i PDB), but it does not provide specific version numbers for any of these software dependencies.
Experiment Setup Yes All experiments were performed on Intel(R) Xeon(R) Gold 6248 CPU @ 2.50GHz machines, with the timeout of 30 minutes and memory limit of 8GB per run.
