Graph sparsification by effective resistances
WebWe examine three types of sparsification: spectral sparsification, which can be seen as the result of sampling edges from the graph with probabilities proportional to their effective resistances, and two simpler sparsifiers, which sample edges uniformly from the graph, either globally or locally. WebBy using effective resistances to define the edge sampling probabilities p e, Spielman and Srivastava 32 proved that every graph has a ((1 + ), O(log n/ 2))-spectral sparsifier. These spectral sparsifiers have a similar number of edges to the cut sparsifiers described in Theorem 1, and many fewer edges than those produced by Spielman and Teng 34 .

A sparsifier of G is a sparse graph on the same vertex set approximating G in some natural way. It allows us to say useful things about G while considering much fewer than m edges. The strongest commonly-used notion of sparsification is spectral sparsification; H is a spectral …

This requires solving the original graph Laplacian multiple times, thus making them impractical for handling real-world big graph problems.
