"WebLemma 5 If each edge weight is increased by 1, the minimum spanning tree doesn’t change Proof: Suppose initially the minimum spanning tree was T. After each edge weight is increased by 1, the minimum spanning tree changes to Tˆ. Therefore there will be at least an edge (u,v) ∈ T but (u,v) ∈/ Tˆ. Suppose we add edge (u,v) to the tree Tˆ.
