Graph sparsification

Webdeleted. The non-adaptive sketches, such as those for sparsification and subgraphs, give us single-pass algorithms for distributed data streams with insertion and deletions. The … WebWe present a general framework for constructing cut sparsifiers in undirected graphs---weighted subgraphs for which every cut has the same weight as the original graph, up to a multiplicative factor of ( 1 ± ϵ). Using this framework, we simplify, unify, and improve upon previous sparsification results.
