WebThe drawback of Dijkstra's Algorithm. A major drawback of Dijkstra's algorithm is that it cannot handle negative edge weights. This happens because Dijkstra's algorithm uses a greedy approach. Whenever the closest node is chosen from the distance array, we mark that node's distance as finalized. We won't ever update that node's distance. create short youtube pcWebA variant of this algorithm is known as Dijkstra’s algorithm. Dijkstra’s Algorithm is an algorithm for finding the shortest paths between nodes in a graph. For a given source node in the graph, the algorithm finds the shortest path between that node and every other node.
