WebThis is done using a technique called "reweighting," which involves adding a constant to all edge weights so that they become non-negative. After finding the minimum spanning tree in the reweighted graph, the constant can be subtracted to obtain the minimum spanning tree in the original graph. WebAug 26, 2014 · Graph reweighting Theorem. Given a label h(v) for each v V, reweight each edge (u, v) E by ŵ(u, v) = w(u, v) + h(u) – h(v). Then, all paths between the same two vertices are reweighted by the same amount. Proof. Let p = v1→ v2→ → vkbe a path in the grah Then, we have. Producing Nonnegative Weights
