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 and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

Pseudocode Yes Algorithm 1 Ellipsoid Est
Open Source Code Yes All the details of experimental settings are explained in Section 7 or Appendix B, and source code is submitted as the supplementary material.
Open Datasets No This paper does not use any datasets.
Dataset Splits No Our experimental settings do not involve train-test split.
Hardware Specification Yes All experiments in Appendix B, including those reported previously, were conducted on a single CPU core with 4 GB of memory and no GPU acceleration, in a cloud environment.
Software Dependencies Yes We use numpy, scipy, matplotlib, jupyterlab, which are explicitly mentioned in pyproject.toml files.
Experiment Setup Yes We choose to set the regularization parameter as λ = (R/S)2. ... We fix ε = 0.1 and study the impact of varying δ (the confidence level) and K (the number of arms).
