WebGraph Sparsification II: Rank one updates, Interlacing, and Barriers Nikhil Srivastava Simons Institute August 26, 2014. Definition. =(𝑉, , )is a −approximation of = 𝑉, , if: … WebAbstract: Graph sparsification underlies a large number of algorithms, ranging from approximation algorithms for cut problems to solvers for linear systems in the graph Laplacian. In its strongest form, “spectral sparsification” reduces the number of edges to near-linear in the number of nodes, while approximately preserving the cut and spectral …
