Question
Chapter 15, Problem 2P
A
Summary Introduction
Interpretation: If, for instance, Corvallis is the starting city, the best route is to be determined using the NN heuristic and the total distance travelled in that route is to be calculated.
Concept Introduction: The Company delivers food items to multiple locations spread across the state. There are a total of 5 customers that the van has to travel to.
B
Summary Introduction
Interpretation: Based on the NNH approach, find out 5 best possible routes, each route starting from one of company’s customer locations, and then determine the best of these 5 routes.
Concept Introduction: The Company delivers food items to multiple locations spread across the state. There are a total of 5 customers that the van has to travel to.
