Allocation problems in ride-sharing platforms: Online matching with offline reusable resources

JP Dickerson, KA Sankararaman… - ACM Transactions on …, 2021 - dl.acm.org
Bipartite-matching markets pair agents on one side of a market with agents, items, or
contracts on the opposing side. Prior work addresses online bipartite-matching markets …

Balancing the tradeoff between profit and fairness in rideshare platforms during high-demand hours

V Nanda, P Xu, KA Sankararaman… - Proceedings of the …, 2020 - ojs.aaai.org
Rideshare platforms, when assigning requests to drivers, tend to maximize profit for the
system and/or minimize waiting time for riders. Such platforms can exacerbate biases that …

Edge-weighted online bipartite matching

M Fahrbach, Z Huang, R Tao, M Zadimoghaddam - Journal of the ACM, 2022 - dl.acm.org
Online bipartite matching is one of the most fundamental problems in the online algorithms
literature. Karp, Vazirani, and Vazirani (STOC 1990) gave an elegant algorithm for …

Improved online contention resolution for matchings and applications to the gig economy

T Pollner, M Roghani, A Saberi, D Wajc - Proceedings of the 23rd ACM …, 2022 - dl.acm.org
Background. Our results tie into the literature on contention resolution schemes [3], which we
briefly define. Let P (𝐺) denote the fractional matching polytope of a graph 𝐺=(𝑉, 𝐸). In a …

Fairness maximization among offline agents in online-matching markets

W Ma, P Xu, Y Xu - ACM Transactions on Economics and Computation, 2023 - dl.acm.org
Online matching markets (OMMs) are commonly used in today's world to pair agents from
two parties (whom we will call offline and online agents) for mutual benefit. However, studies …

Trading the system efficiency for the income equality of drivers in rideshare

Y Xu, P Xu - arxiv preprint arxiv:2012.06850, 2020 - arxiv.org
Several scientific studies have reported the existence of the income gap among rideshare
drivers based on demographic factors such as gender, age, race, etc. In this paper, we study …

Improved guarantees for offline stochastic matching via new ordered contention resolution schemes

B Brubach, N Grammel, W Ma… - Advances in Neural …, 2021 - proceedings.neurips.cc
Matching is one of the most fundamental and broadly applicable problems across many
domains. In these diverse real-world applications, there is often a degree of uncertainty in …

Multi-stage and multi-customer assortment optimization with inventory constraints

E Fata, W Ma, D Simchi-Levi - arxiv preprint arxiv:1908.09808, 2019 - arxiv.org
We consider an assortment optimization problem where a customer chooses a single item
from a sequence of sets shown to her, while limited inventories constrain the items offered to …

Random-order contention resolution via continuous induction: Tightness for bipartite matching under vertex arrivals

C MacRury, W Ma - Proceedings of the 56th Annual ACM Symposium on …, 2024 - dl.acm.org
We introduce a new approach for designing Random-order Contention Resolution Schemes
(RCRS's) via exact solution in continuous time. Given a function c (y):[0, 1]→[0, 1], we show …

Online matching with delays and stochastic arrival times

M Mari, M Pawłowski, R Ren, P Sankowski - Theory of Computing Systems, 2025 - Springer
Consider a platform where independent agents arrive at random times and need to be
matched into pairs, eventually after waiting for some time. This, for example, models job …
