  1. Define the terms
    1. tree,
    2. minimum spanning tree.
  2. Use Prim's algorithm, starting at A , to find a minimum spanning tree for the network shown in Figure 1. You must clearly state the order in which you select the arcs of the tree.
  3. Draw the minimum spanning tree using the vertices given in Diagram 1 in the answer book and state the weight of the tree.
