Web2 Graph reduction and coarsening The following section introduces graph reduction. The exposition starts by considering a general reduction scheme. It is then shown how graph coarsening arises naturally if one additionally imposes requirements w.r.t. the interpretability of reduced variables. 2.1 Graph reduction WebJan 21, 2014 · 8 Answers. Sorted by: 80. Yes, it does. One method for computing the maximum weight spanning tree of a network G – due to Kruskal – can be summarized as follows. Sort the edges of G into decreasing order by weight. Let T be the set of edges comprising the maximum weight spanning tree. Set T = ∅. Add the first edge to T.
