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]

Reproducibility Variable Result LLM Response
Research Type Theoretical We compute the exact worst-case adaptive regret of Fixed Share. We re-derive the tracking regret bounds from these adaptive regret bounds, showing that the latter are in fact more fundamental. We prove that Fixed Share is optimal for adaptive regret: the worst-case adaptive regret of any algorithm is at least that of an instance of Fixed Share.
