Question 3 (30 points): a. (15 Points) (Minimal Spanning Tree Method) The CCP Company needs to connect & mainframe (A-H) computers with cables in a network as shown in the Figure below. The network can take any form, as long as each computer is connected with at least one other computer. All physically possible connections between nodes are shown in the figure below with distances in km.s indicated at each cable. Realize the network at minimum cost, which means a minimal total length of cables. 300 B 500 A 200 400 300 200 300 E SOO (F D 500 400 200 1600 (H b.
