                        Dijkstra's algorithm may produce incorrect results when the graph contains negative edges, because it greedily selects vertices with the current shortest path and cannot handle situations where the total path weight might decrease due to negative edges.
                        <br><br>
                        The Floyd-Warshall algorithm is a dynamic programming-based all-pairs shortest path algorithm that can handle negative edges, but not negative cycles. The Bellman-Ford algorithm is specifically designed to handle single-source shortest path problems in graphs with negative edges.
