Which of the following is not a dynamic programming problem?a)Fibonacc...
Shortest path in a graph is not a dynamic programming problem because:
- Definition:
- Dynamic programming involves breaking down a problem into smaller subproblems and solving each subproblem just once, storing the solution to each subproblem to avoid redundant calculations.
- Shortest path in a graph, on the other hand, typically involves finding the minimum cost path from one node to another in a graph, which is better solved using algorithms like Dijkstra's algorithm or Bellman-Ford algorithm.
- Complexity:
- Dynamic programming problems usually involve overlapping subproblems and optimal substructure, which can be exploited to solve the problem efficiently. Shortest path problems in graphs do not necessarily exhibit these characteristics, making them more suited for graph algorithms rather than dynamic programming.
- Optimal Substructure:
- Dynamic programming problems can be solved by combining solutions to subproblems to form a solution to the original problem. In contrast, the shortest path problem in a graph does not directly lend itself to this approach, as the optimal path may not necessarily be composed of optimal subpaths.
In conclusion, while dynamic programming is a powerful technique for solving a wide range of problems, the shortest path problem in a graph is better addressed using specialized graph algorithms designed specifically for this purpose.
