Online graph algorithms with predictions

Y Azar, D Panigrahi, N Touitou - Proceedings of the 2022 Annual ACM-SIAM …, 2022 - SIAM
Online algorithms with predictions is a popular and elegant framework for bypassing
pessimistic lower bounds in competitive analysis. In this model, online algorithms are …

Fully dynamic consistent facility location

V Cohen-Addad, NOD Hjuler… - Advances in …, 2019 - proceedings.neurips.cc
We consider classic clustering problems in fully dynamic data streams, where data elements
can be both inserted and deleted. In this context, several parameters are of importance:(1) …

A universal error measure for input predictions applied to online graph problems

G Bernardini, A Lindermayr… - Advances in …, 2022 - proceedings.neurips.cc
We introduce a novel measure for quantifying the error in input predictions. The error is
based on a minimum-cost hyperedge cover in a suitably defined hypergraph and provides a …

Learning augmented online facility location

D Fotakis, E Gergatsouli, T Gouleakis… - arxiv preprint arxiv …, 2021 - arxiv.org
Following the research agenda initiated by Munoz & Vassilvitskii [1] and Lykouris &
Vassilvitskii [2] on learning-augmented online algorithms for classical online optimization …

Online and incremental algorithms for facility location

D Fotakis - ACM SIGACT News, 2011 - dl.acm.org
In the online and incremental variants of Facility Location, the demands arrive one-by-one
and must be assigned to an open facility upon arrival, without any knowledge about future …

[HTML][HTML] Offline and online facility leasing

C Nagarajan, DP Williamson - Discrete Optimization, 2013 - Elsevier
We study the problem of leasing facilities over time, following the general infrastructure
leasing problem framework introduced by Anthony and Gupta (2007). If there are K different …

Almost tight bounds for online facility location in the random-order model

H Kaplan, D Naori, D Raz - Proceedings of the 2023 Annual ACM-SIAM …, 2023 - SIAM
We study the online facility location problem with uniform facility costs in the random-order
model. Meyerson's algorithm [FOCS'01] is arguably the most natural and simple online …

Discrete-smoothness in online algorithms with predictions

Y Azar, D Panigrahi, N Touitou - Advances in Neural …, 2024 - proceedings.neurips.cc
In recent years, there has been an increasing focus on designing online algorithms with
(machine-learned) predictions. The ideal learning-augmented algorithm is comparable to …

Online facility location with deletions

M Cygan, A Czumaj, M Mucha, P Sankowski - arxiv preprint arxiv …, 2018 - arxiv.org
In this paper we study three previously unstudied variants of the online Facility Location
problem, considering an intrinsic scenario when the clients and facilities are not only …

Towards the price of leasing online

S Abshoff, P Kling, C Markarian… - Journal of Combinatorial …, 2016 - Springer
We consider online optimization problems in which certain goods have to be acquired in
order to provide a service or infrastructure. Classically, decisions for such problems are …
