Almost-Linear Time Algorithms for Incremental Graphs: Cycle Detection, SCCs, $s$ - $t$ Shortest Path, and Minimum-Cost Flow

Li Chen, Rasmus Kyng, Yang P. Liu +2

We give the first almost-linear time algorithms for several problems in incremental graphs including cycle detection, strongly connected component maintenance, $s$ - $t$ shortest pat…

Incremental Approximate Maximum Flow on Undirected Graphs in Subpolynomial Update Time

Jan van den Brand, Li Chen, Rasmus Kyng +5

We provide an algorithm which, with high probability, maintains a $(1 - ε)$ -approximate maximum flow on an undirected graph undergoing $m$ -edge additions in amortized $m^{o(1)} ε^{-3…
