Which of the following standard algorithm is not an greedy algorithm?...
Explanation:
Bellman-Ford Shortest Path Algorithm:
- Bellman-Ford algorithm is not a greedy algorithm.
- It is used to find the shortest path from a single source vertex to all other vertices in a weighted graph.
- The algorithm works by relaxing edges repeatedly, updating the shortest distances until the optimal solution is found.
- Unlike greedy algorithms, Bellman-Ford considers all possible paths to find the shortest path, making it a dynamic programming approach rather than a greedy one.
Greedy Algorithms:
- Greedy algorithms make locally optimal choices at each step with the hope of finding a global optimum solution.
- Examples of greedy algorithms include Huffman encoding, Kruskal's algorithm, and Dijkstra's shortest path algorithm.
- Greedy algorithms are characterized by their step-by-step decision-making process, where each decision is made based on the current best option without revisiting previous choices.
- In contrast, Bellman-Ford algorithm does not follow the greedy strategy as it considers all possible paths and updates the distances iteratively.
Therefore, Bellman-Ford shortest path algorithm is not a greedy algorithm, unlike the other options provided in the question.
