A tale of Santa Claus, hypergraphs and matroids

S Davies, T Rothvoss, Y Zhang - Proceedings of the Fourteenth Annual ACM …, 2020 - SIAM
A well-known problem in scheduling and approximation algorithms is the Santa Claus
problem. Suppose that Santa Claus has a set of gifts, and he wants to distribute them among …

Better trees for santa claus

É Bamas, L Rohwedder - Proceedings of the 55th Annual ACM …, 2023 - dl.acm.org
We revisit the problem max-min degree arborescence, which was introduced by Bateni et
al.[STOC'09] as a central special case of the general Santa Claus problem, which constitutes …

Lift-and-Project Integrality Gaps for Santa Claus

E Bamas - Proceedings of the 2025 Annual ACM-SIAM …, 2025 - SIAM
This paper is devoted to the study of the MaxMinDegree Arborescence (MMDA) problem in
layered directed graphs of depth ℓ≤ O (log n/log log n), which is an important special case …

Inapproximability results for scheduling with interval and resource restrictions

M Maack, K Jansen - arXiv preprint arXiv:1907.03526, 2019 - arxiv.org
In the restricted assignment problem, the input consists of a set of machines and a set of jobs
each with a processing time and a subset of eligible machines. The goal is to find an …

[HTML][HTML] Structural parameters for scheduling with assignment restrictions

K Jansen, M Maack, R Solis-Oba - Theoretical Computer Science, 2020 - Elsevier
We consider scheduling on identical and unrelated parallel machines with job assignment
restrictions. These problems are NP-hard and they do not admit polynomial time …

Truthful allocation in graphs and hypergraphs

G Christodoulou, E Koutsoupias, A Kovács - arXiv preprint arXiv …, 2021 - arxiv.org
We study truthful mechanisms for allocation problems in graphs, both for the minimization
(ie, scheduling) and maximization (ie, auctions) setting. The minimization problem is a …

On the Min-Max Star Partitioning Number

S Feldmann, T Schürenberg - International Symposium on Algorithmics of …, 2024 - Springer
In this paper, we introduce a novel star partitioning problem for simple connected graphs
G=(V, E). The goal is to find a partition of the edges into stars that minimizes the maximum …

Unrelated Machine Scheduling in Different Information Models

A Lindermayr - 2024 - media.suub.uni-bremen.de
Unrelated machines are an abstraction of many scheduling environments appearing in
practical applications, where every job may be processed at a different speed on every …

Approximation algorithms for problems in makespan minimization on unrelated parallel machines

DR Page - 2019 - search.proquest.com
A fundamental problem in scheduling is makespan minimization on unrelated parallel
machines (R|| C max). Let there be a set J of jobs and a set M of parallel machines, where …

[图书][B] Approximation Algorithms for Scheduling and Fair Allocations

Y Zhang - 2022 - search.proquest.com
In this thesis, we will have discussions on two main topics, max-min allocation and
scheduling jobs with precedent constraints on machines with communication delays. New …
