arXiv:2605.20854v1 Announce Type: new Abstract: We study a stochastic bandit algorithm motivated by retry-aware objectives that value the best outcome among multiple attempts, such as pass@$k$ and max@$k$. Given a posterior over arm values, ReMax chooses a sampling distribution that maximizes the posterior expected maximum reward over $M$ virtual draws. Although this objective was introduced in reinforcement learning as an exploration mechanism under uncertainty, its regret properties in bandit problems have remained unclear. For Gaussian rewards and the first nontrivial case $M=2$, we charact
This is a typical arXiv pre-print demonstrating incremental academic progress in machine learning theory.
For a sophisticated reader, this theoretical work on bandit algorithms is a niche academic development without immediate strategic implications.
This publication provides a specific regret analysis for a particular bandit algorithm (ReMax) under certain conditions, extending theoretical understanding within its domain.
Further academic research in reinforcement learning and bandit theory may build upon this analysis.
Improved theoretical understanding could eventually contribute to more robust exploration strategies in complex AI systems.
These theoretical advancements might underpin future AI agent designs, though this is far removed and highly speculative.
