Pseudocode No The paper does not include any structured pseudocode or algorithm blocks.
Open Source Code No The paper does not provide any concrete access to source code, such as a repository link or an explicit statement about code release.
Open Datasets No The paper describes generating its own data: 'the feature variable u is drawn from a normal distribution: u N [0.5, 0.5, ..., 0.5]T , 0.5Imu ; and the label variable y is generated via a linear model: y = u x + e'. No public dataset access information (link, DOI, or specific citation to a pre-existing dataset) is provided.
Dataset Splits No The paper mentions 'training data' but does not provide specific dataset split information (e.g., percentages, sample counts, or methodology for creating train/validation/test sets) needed to reproduce data partitioning.
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, memory, or cloud instance types) used for running its experiments.
Software Dependencies No The paper does not specify any software dependencies with version numbers (e.g., library names like PyTorch 1.9, or solver names like CPLEX 12.4).
Experiment Setup Yes For this purpose, we consider a relatively highdimensional setting with the dimension mu = 10 and the true model parameter x = x = [2.0, 1.0, ..., 2.0, 1.0]T .We vary the tolerance rate ϵ in the RS model and the radius r in the DRO model. We set the model parameter in the sampling distribution to x = [2.0, 1.0]T , as in Section 5.2; and set the target environment to be x = [1.80, 0.90]T .
