Determining 4-Edge-Connected Components in Linear Time

Authors: Wojciech Nadara, Mateusz Radecki, Marcin Smulewicz, and Marek Sokołowski

Abstract
In this work, we present the first linear time deterministic algorithm computing the 4-edge-connected components of an undirected graph. First, we show an algorithm listing all 3-edge-cuts in a given 3-edge-connected graph, and then we use the output of this algorithm in order to determine the 4-edge-connected components of the graph.
