WebDec 30, 2012 · This works for undirected graphs with positive edges and arbitrary directed graphs, because in those graphs, any prefix of a shortest path is another shortest path. But shortest paths in undirected graphs with negative edges don't necessarily define trees. Consider the following simple example: WebIn computer science, Prim's algorithm (also known as Jarník's algorithm) is a greedy algorithm that finds a minimum spanning tree for a weighted undirected graph.This means it finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized. The algorithm operates by building this …

And if you’re running Floyd–Warshall algorithm on such directed graph – it would work correctly, as always. Actually this algorithm is so amazing that it works for both directed and undirected graph.
WebAug 20, 2024 · Dijkstra's algorithm never works when there is a negative weight cycle. If a graph has negative weights, but no negative weight cycles, it is possible to modify the graph into a graph where Dijkstra can be applied and the results transformed to find shortest paths in the original graph. One such technique is known as Johnson's …
