WebApr 26, 2012 · Let G be a graph with n vertices and m edges. 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 … WebMay 10, 2024 · Abstract. In this paper, we draw on Spielman and Srivastava’s method for graph sparsification in order to simplify shape representations. The underlying principle …

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 . 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. sidney gomes
