AdaSwitch: An Adaptive Switching Meta-Algorithm for Learning-Augmented Bounded-Influence Problems

The paper introduces AdaSwitch, a meta‑algorithm for history‑dependent online problems where predictions of future requests may be inaccurate. It operates within a bounded‑influence framework, where past decisions only affect future optimal values by a limited amount, and it adaptively switches between offline and online oracles. AdaSwitch guarantees expected performance that improves as prediction error shrinks or the offline optimum grows, while maintaining a near‑optimal worst‑case bound under arbitrary predictions. The authors demonstrate its applicability to online lead‑time quotation, k‑server and caching, and online reusable resource allocation for both reward maximization and cost minimization.

Blackwell Approachability and Gradient Equilibrium are Equivalent

arXiv:2606. 27315v1 Announce Type: new Abstract: Gradient equilibrium (GEQ) is a recently introduced online optimization framework that generalizes first-order stationarity from offline optimization and abstracts problems like online conformal prediction.
