A Scaling Algorithm for Weighted $f$ -Factors in General Graphs

Ran Duan, Haoqing He, Tianyi Zhang

We study the maximum weight perfect $f$ -factor problem on any general simple graph $G = (V, E, w)$ with positive integral edge weights $w$ , and $n = ∣ V ∣$ , $m = ∣ E ∣$ . When we have a functio…

Approximate Distance Oracles Subject to Multiple Vertex Failures

Ran Duan, Yong Gu, Hanlin Ren

Given an undirected graph $G = (V, E)$ of $n$ vertices and $m$ edges with weights in $[1, W]$ , we construct vertex sensitive distance oracles (VSDO), which are data structures that pre…
