Flexibility allocation in random bipartite matching markets: exact matching rates and dominance regimes

Taha Ameen, Flore Sentenac, Sophie H. Yu

This paper studies how a fixed flexibility budget should be allocated across the two sides of a balanced bipartite matching market. We model compatibilities via a sparse bipartite…

Detection of local geometry in random graphs: information-theoretic and computational limits

Jinho Bok, Shuangping Li, Sophie H. Yu

We study the problem of detecting local geometry in random graphs. We introduce a model $G (n, p, d, k)$ , where a hidden community of average size $k$ has edges drawn as a…
