Bounded degree group steiner tree problems

G Kortsarz, Z Nutov - International Workshop on Combinatorial Algorithms, 2020 - Springer
Motivated by some open problems posed in 13, we study three problems that seek a low

Online Decision Making via Prophet Setting

S Ehsani - 2017 - search.proquest.com
In the study of online problems, it is often assumed that there exists an adversary who acts
against the algorithm and generates the most challenging input for it. This worst-case …
