Dijkstra’s algorithm can work on both directed and undirected graphs, but … WebJan 18, 2024 · Unfortunately, standard low-diameter decomposition algorithms only work on undirected graphs — those in which every edge can be traversed in both directions. The negative-weight shortest-paths problem, meanwhile, only makes sense on directed graphs, in which every edge is a one-way street. 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.
