Does dijkstra work with negative edges
WebYes,you are right Prim's algorithm works like dijkstra's algorithm but in prim's algorithm it should not compute shortest path from i to j having negative edges . So, their is an another algorithm is their i.e Bellman-Ford algorithm for compute shortest path from i to j with negative edge. WebThe Dijkstra’s algorithm does not work and does not generate correct results in case the graph contains edges with negative costs. Even if the graph does not contain negative cost cycles, but only negative edge cost, then, also the algorithm does not produce correct results. In this, start from one vertex, and explore the graph by traversing ...
Does dijkstra work with negative edges
Did you know?
WebThe thick edges in the previous figure show the shortest paths from the root v 0 to every other node. They form a spanning tree that includes every vertex in the graph and shows the minimum distance to each of them. Performance of Dijkstra's algorithm. The algorithm does some work per vertex and some work per edge.
