Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in [1]

Pseudocode Yes Algorithm 1 Perturbed Gradient Descent [Jin et al., 2017]
Open Source Code No The paper does not provide any explicit statements about releasing source code or links to a code repository.
Open Datasets No The paper defines an objective function for its experiments (equations 14 and 15 in the Appendix) rather than using a publicly available dataset. Therefore, no concrete access information for a dataset is provided.
Dataset Splits No The paper uses a custom-defined objective function for its experiments, not a standard dataset. Therefore, no information on training/validation/test splits is provided.
Hardware Specification No The paper does not provide any specific details about the hardware used for running the experiments.
Software Dependencies No The paper mentions parameters like stepsize, tthres, gthres, and r, but does not specify any software names with version numbers used for the experiments.
Experiment Setup Yes For both GD and PGD we let the stepsize η = 1 4L. For PGD, we choose tthres = 1, gthres = γe 100 and r = e 100. In Figure 3 we fix dimension d = 5 and vary L as considered in Section 4.1; similarly in Figure 4 we choose d = 10 and vary L.
