Question number 25 only please. Question 21 provided for help
21. When installing fiber optics, some companies will install a sonet ring; a full loop of cable connecting multiple locations. This is used so that if any part of the cable is damaged it does not interrupt service, since there is a second connection to the hub. A company has 5 buildings. Costs (in thousands of dollars) to lay cables between pairs of buildings are shown below. Find the circuit that will minimize cost: a. Using Nearest Neighbor starting at building A b. Using Repeated Nearest Neighbor c. Using Sorted Edges B $6.0 C $5.9 $5.1 -$5.2 $4.3 A -$5.6 $4.4 $4.0 $4.7 $5.8 D E
