New algorithm tackles online budget allocation with censored feedback

Researchers have developed a new algorithm for online budget allocation problems with censored semi-bandit feedback. This algorithm, based on optimism, operates with an exact maximization oracle and achieves instance-dependent bounds that scale polylogarithmically with the horizon in diminishing-returns regimes. For more general nondecreasing curves, the algorithm provides a worst-case regret upper bound of $\tilde O(K\sqrt{T})$, which is matched by a lower bound, indicating the inherent difficulty of the problem outside of diminishing returns.

    Online Budget Allocation with Censored Semi-Bandit Feedback

    arXiv:2508.05844v3 Announce Type: replace-cross Abstract: We study a stochastic budget-allocation problem over $K$ tasks. At each round $t$, the learner chooses an allocation $X_t \in \Delta_K$. Task $k$ succeeds with probability $F_k(X_{t,k})$, where $F_1,\dots,F_K$ are nondecre…
