Questions and Answers

Which of the following scenarios would be best suited for solving using dynamic programming?

Determining the optimal order to visit a set of cities to minimize total travel distance.

Finding the shortest path between two points in a dense city map.

Managing inventory levels for a product with fluctuating demand. (correct)

Scheduling maintenance tasks for a fleet of vehicles to minimize downtime.

Which of the following is NOT a key step in the dynamic programming process?

Identifying the states within each stage.

Calculating the optimal path from each state to the destination.

Using a shortest path algorithm, like Dijkstra's, to find the optimal solution. (correct)

Why is dynamic programming a better approach for finding optimal paths in a multi-stage network compared to Dijkstra's algorithm?

Dijkstra's algorithm is only suitable for finding shortest paths, not optimal paths in general.

Dynamic programming is computationally more efficient for large networks.

Dynamic programming considers the cumulative effect of decisions across stages, while Dijkstra's algorithm is limited to individual path segments. (correct)

Dynamic programming can handle more complex network structures with cycles.
