While 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) to lay cables between pairs of buildings are shown below. B $6.0 $5.9 $5.1 -$5.2 $4.3 -$5.6 $4.4 $4.0 $4.7 $5.8 E C D a. Find the circuit that will minimize cost using Nearest Neighbor starting at building A. b. Find the circuit that will minimize cost using Sorted Edges (starting with CE).
