Prophet secretary for combinatorial auctions and matroids

S Ehsani, MT Hajiaghayi, T Kesselheim… - Proceedings of the twenty …, 2018 - SIAM

Robust algorithms for the secretary problem

D Bradac, A Gupta, S Singla, G Zuzic - arxiv preprint arxiv:1911.07352, 2019 - arxiv.org
In classical secretary problems, a sequence of $ n $ elements arrive in a uniformly random
