Pseudocode No The paper describes the algorithm steps in text but does not provide a formal pseudocode block or algorithm figure.
Open Source Code Yes Code at https://gitlab.com/ckatsimerou/abc_s_public
Open Datasets No The paper mentions using "real data collected from an A/B/n experiment" and synthetically generated data, but does not provide access information (link, DOI, citation) for a publicly available dataset.
Dataset Splits No The paper does not explicitly provide training/validation/test dataset splits needed to reproduce the experiment.
Hardware Specification No The paper does not specify any hardware used for running the experiments (e.g., GPU models, CPU types, or cloud instance details).
Software Dependencies No The paper does not provide specific software dependencies with version numbers (e.g., library names with versions).
Experiment Setup Yes In our second experiment 1, we generated 3000 Bernoulli bandit instances with K = 2 and a random number of subpopulations J between 2 and 10. Each subpopulation-arm s mean µa,i is drawn uniformly at random from [0, 1], and the subpopulation frequency vector α is drawn from a Dirichlet(10) distribution.
