Both of these functions solve the single source shortest path problem. The primary difference in the function of the two algorithms is that Dijkstra's algorithm cannont handle negative edge weights. Bellman-Ford's algorithm can handle some edges with negative weight. It must be remembered, however, that if there is a negative cycle there is no shortest path.
dijkstra's algorithm (note* there are different kinds of dijkstra's implementation) and growth graph algorithm
The Bellman-Ford algorithm works by repeatedly relaxing the edges of the graph, updating the shortest path estimates until the optimal shortest path is found. It can handle graphs with negative edge weights, unlike Dijkstra's algorithm.
The Floyd-Warshall algorithm finds the shortest paths between all pairs of vertices in a graph, while the Bellman-Ford algorithm finds the shortest path from a single source vertex to all other vertices. Floyd-Warshall is more efficient for dense graphs with many edges, while Bellman-Ford is better for sparse graphs with fewer edges.
The key difference between the Bellman-Ford and Floyd-Warshall algorithms is their approach to finding the shortest paths in a graph. Bellman-Ford is a single-source shortest path algorithm that can handle negative edge weights, but it is less efficient than Floyd-Warshall for finding shortest paths between all pairs of vertices in a graph. Floyd-Warshall, on the other hand, is a dynamic programming algorithm that can find the shortest paths between all pairs of vertices in a graph, but it cannot handle negative cycles. In summary, Bellman-Ford is better for single-source shortest path with negative edge weights, while Floyd-Warshall is more efficient for finding shortest paths between all pairs of vertices in a graph.
The key differences between the Floyd-Warshall and Bellman-Ford algorithms are in their approach and efficiency. The Floyd-Warshall algorithm is a dynamic programming algorithm that finds the shortest paths between all pairs of vertices in a graph. It is more efficient for dense graphs with many edges. The Bellman-Ford algorithm is a single-source shortest path algorithm that finds the shortest path from a single source vertex to all other vertices in a graph. It is more suitable for graphs with negative edge weights. In summary, Floyd-Warshall is better for finding shortest paths between all pairs of vertices in dense graphs, while Bellman-Ford is more suitable for graphs with negative edge weights and finding shortest paths from a single source vertex.
This distance-vector algorithm works by computing the shortest path , and considers weights. The algorithm was distributed widely in the RIP protocol.
The shortest path in a directed graph between two nodes is the path with the fewest number of edges or connections between the two nodes. This path is determined by algorithms like Dijkstra's or Bellman-Ford, which calculate the shortest distance between nodes based on the weights assigned to the edges.
Cisco uses DUAL FSM (EIGRP) to make sure that on a global level a route is recalculated when the possibility exists that it might cause a routing loop. In essence, this attempts to prevent routing loops. Other algorithms used in path calculation are the Bellman-Ford (shortest path) and Ford-Fulkerson (maximum flow).

No, it is not.
To formulate the shortest path problem as a linear program, you can assign variables to represent the decision of which paths to take, and set up constraints to ensure that the total distance or cost of the chosen paths is minimized. The objective function would be to minimize the total distance or cost, and the constraints would include ensuring that the chosen paths form a valid route from the starting point to the destination. This linear program can then be solved using optimization techniques to find the shortest path.
