Threshold testing and semi-online prophet inequalities

M Hoefer, K Schewior - 31st Annual European …, 2023 - portal.findresearcher.sdu.dk
We study threshold testing, an elementary probing model with the goal to choose a large
value out of n iid random variables. An algorithm can test each variable ** and online decision-making.
Traditionally, they involve the sequential observation of $ n $ non-negative independent …

On Augmented Stochastic Submodular Optimization: Adaptivity, Multi-Rounds, Budgeted, and Robustness

V Auletta, D Ferraioli, C Vinci - CEUR Workshop Proceedings, 2022 - iris.unisalento.it
In this work we consider the problem of Stochastic Submodular Maximization, in which we
would like to maximize the value of a monotone and submodular objective function, subject …
