When the queue in this algorithm is implemented with a linear array, it can be shown to run in Big O of V squared, so a Fibonacci heap is sometimes used instead to reduce its running time to Big O of quantity E plus V log V. By relaxing all entities at each step, the Bellman-Ford algorithm handles the case of negative weights where this algorithm breaks down.

By relaxing all entities at each step, the Bellman-Ford algorithm handles the case of negative weights where this algorithm breaks down. A generalization of this algorithm using a distance heuristic is called A [A Star], and this algorithm initially sets the distance to all vertexes to be infinity. It functions in a greedy manner by selecting the edge with the smallest known weight to a node that has not yet been visited. FTP, identify this algorithm that finds the single source shortest paths in a graph, named for its Dutch formulator.
