Online Service with Per-Batch Maximum Delay

Tianhang Lu, Runtian Ren, Shengcai Liu +1

We study online service with one maximum-waiting-time charge per service batch. The persistent server endpoint prevents a phase-by-phase comparison with the offline optimum: an off…

Online Multi-Level Aggregation with Per-Batch Maximum Delay

Tianhang Lu, Runtian Ren, Shengcai Liu +1

We study online multi-level aggregation on finite rooted trees with a per-batch maximum-delay objective. A service pays for a rooted subtree and for the maximum waiting time among…

Learning-Augmented and Randomized Algorithms for Line Aggregation with Delays

Tianhang Lu, Runtian Ren, Shengcai Liu +1

The paper designs deterministic and randomized online algorithms for line aggregation with delays, incorporating learning-augmented advice and analyzing their robustness, consisten…

Learning-Augmented Algorithms for Online Vertex Cover

Tianhang Lu, Runtian Ren, Shengcai Liu

This paper studies learning-augmented online weighted vertex cover with local advice and a tradeoff parameter . We consider two graph settings: bipartite graphs and ge…

Online Multi-level Aggregation with Delays and Stochastic Arrivals

Mathieu Mari, Michał Pawłowski, Runtian Ren +1

This paper presents a new research direction for online Multi-Level Aggregation (MLA) with delays. In this problem, we are given an edge-weighted rooted tree , and we have to se…
