Minimum-weight spanning trees

WebProblem 2-1. Unique Minimum Spanning Trees. In Lecture 3, we saw the claim that any weighted undirected graph with distinct edge weights has exactly one minimum spanning tree. In this problem, your goal will be to show that this claim is true by proving a more general theorem. WebA Spanning Tree (ST) of a connected undirected weighted graph G is a subgraph of G that is a tree and connects (spans) all vertices of G. A graph G can have many STs (see this …
