[PDF][PDF] Limitations of stochastic selection problems with pairwise independent priors

S Dughmi, YH Kalayci, N Patel - Proceedings of the 56th Annual ACM …, 2024 - dl.acm.org
Motivated by the growing interest in correlation-robust stochastic optimization, we
investigate stochastic selection problems beyond independence. Specifically, we consider …

Combinatorial stationary prophet inequalities

N Patel, D Wajc - Proceedings of the 2024 Annual ACM-SIAM …, 2024 - SIAM
Numerous recent papers have studied the tension between thickening and clearing a
market in (uncertain, online) long-time horizon Markovian settings. In particular,(Aouad and …

Deterministic Online Bipartite Edge Coloring

J Blikstad, O Svensson, R Vintan, D Wajc - … of the 2025 Annual ACM-SIAM …, 2025 - SIAM
We study online bipartite edge coloring, with nodes on one side of the graph revealed
sequentially. The trivial greedy algorithm is (2—o (1))-competitive, which is optimal for …

Query efficient weighted stochastic matching

M Derakhshan, M Saneian - arxiv preprint arxiv:2311.08513, 2023 - arxiv.org
In this paper, we study the weighted stochastic matching problem. Let $ G=(V, E) $ be a
given edge-weighted graph and let its realization $\mathcal {G} $ be a random subgraph of …

Limitations of Stochastic Selection with Pairwise Independent Priors

S Dughmi, YH Kalayci, N Patel - arxiv preprint arxiv:2310.05240, 2023 - arxiv.org
Motivated by the growing interest in correlation-robust stochastic optimization, we
investigate stochastic selection problems beyond independence. Specifically, we consider …

Query Complexity of Stochastic Minimum Vertex Cover

M Derakhshan, M Saneian, Z Xun - 16th Innovations in …, 2025 - drops.dagstuhl.de
We study the stochastic minimum vertex cover problem for general graphs. In this problem,
we are given a graph G=(V, E) and an existence probability p_e for each edge e∈ E. Edges …

[PDF][PDF] From Contention Resolution to Matroid Secretary and Back

S Dughmi - 2024 - viterbi-web.usc.edu
We show that the matroid secretary problem is equivalent to correlated contention resolution
in the online random-order model. Specifically, the matroid secretary conjecture is true if and …
