Abstract:Cuts in graphs are a fundamental object of study, and play a central role in the study of graph algorithms. The problem of sparsifying a graph while approximately preserving its cut structure has been extensively studied and has many applications. In a seminal work, Benczr and Karger (1996) showed that given any n-vertex undirected weighted graph G and a parameter ε ∈ (0, 1), there is a near-linear time algorithm that outputs a weighted subgraph G ′ of G of size Õ(n/ε 2 ) such that the weight of every cut in … Show more
