Computational bounds on randomized algorithms for online bin stretching

A Lhomme, N Catusse, N Brauner - arxiv preprint arxiv:2405.19071, 2024 - arxiv.org
A frequently studied performance measure in online optimization is competitive analysis. It
corresponds to the worst-case ratio, over all possible inputs of an algorithm, between the …

Improved online load balancing with known makespan

M Böhm, M Lieskovský, S Schmitt, J Sgall… - arxiv preprint arxiv …, 2024 - arxiv.org
We break the barrier of $3/2$ for the problem of online load balancing with known
makespan, also known as bin stretching. In this problem, $ m $ identical machines and the …
