You need to take a trip by car to another town that you have never visited before. Therefore, you are studying a map to determine the shortest route to your destination. Depending on which route you choose, there are five other towns (call them A, B, C, D, E) that you might pass through on the way. The map shows the mileage along each road that directly connects two towns without any intervening towns. These numbers are summarized in the following table, where a dash indicates that there is no road directly connecting these two towns without going through any other towns. Town A Origin 40 ABCDE Miles between Adjacent Towns B C D E 60 10 50 20 70 55 - ०४५।। 40 50 10 Destination ||||88 60 80 (a) Formulate this problem as a shortest-path problem by drawing a network where nodes represent towns, links represent roads, and numbers indicate the length of each link in miles. (b) Use the Dijkstra's algorithm to solve this shortest path problem. Illustrate your work by using a table. (c) If each number in the table represented your cost (in dollars) for driving your car from one town to the next, would the answer in part (b) now give your minimum cost route? (d) If each number in the table represented your time (in minutes) for driving your car from one town to the next, would the answer in part (b) now give your minimum time route?
