Webof edges must be different. So, let e* be the smallest cost edge in T1 that is not in T2. Deleting that edge from T1 would disconnect T1 into two components. Since T1 chose that edge, it must be the smallest cost crossing edge for those two components. But by the cut property, that edge must therefore belong to every minimum spanning tree. WebA minimum spanning tree can be defined as the spanning tree in which the sum of the weights of the edge is minimum. The weight of the spanning tree is the sum of the …
