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.

Study Notes
Dynamic Programming
- Bellman's principle of optimality states that any section of an optimal path is itself optimal.
- Dynamic programming is used to find minimum or maximum path solutions based on this principle.
- It is a better method than Dijkstra's algorithm when the network is split into stages.
Steps for Dynamic Programming
- Work backwards from the final node (destination) and label it as stage 1.
- Identify each vertex immediately before the destination and label them as states.
- Calculate the values to go from each state to the destination.
- Mark the best route from each node to the destination (optimal paths).
- Repeat the process for each node at the end of each stage until reaching the source node.
