WebThe main advantage of bellman ford algorithm is its capability to handle negative weights. The drawback is that it cannot find a solution if there exists a negative weight cycle in the graph. A negative cycle reduces the path value by coming back to the same vertex. WebAnswer: No, the Bellman Ford algorithm is not a greedy algorithm because it does not always choose the locally optimal solution at each step. Q6. Can the Bellman Ford … WebViewed 888 times. 1.
