TopicMinimum Spanning Trees

3
    1. State the number of edges in a minimum spanning tree of a network with 11 vertices.
    2. State the number of edges in a minimum spanning tree of a network with \(n\) vertices.
  1. The following network has 11 vertices, \(A , B , \ldots , K\). The number on each edge represents the distance, in miles, between a pair of vertices.

    1. Use Prim's algorithm, starting from \(A\), to find a minimum spanning tree for the network.
    2. Find the length of your minimum spanning tree.
    3. Draw your minimum spanning tree.
