Identifying All {epsilon}-Best Arms in (Misspecified) Linear Bandits arXiv:2510.00073v1 Announce Type: new Abstract: Motivated by the need to efficiently identify multiple candidates in high trial-and-error cost tasks such as drug discovery, we propose a near-optimal algorithm to identify all {epsilon}-best arms (i.e., those at most {epsilon} worse than the optimum). Specifically, we introduce LinFACT, an…
