WebFeb 18, 2024 · Dijkstra algorithm can find the shortest distance in both directed and undirected weighted graphs. This Algorithm is greedy because it always chooses the shortest or closest node from the origin. The term “greedy” means that among a set of outcomes or results, the Algorithm will choose the best of them. WebHere’s how the algorithm is implemented: Mark all nodes as unvisited. Mark the initially selected node with the current distance of. 0. 0 0 and the rest with infinity. Set the initial node as the current node. For the current node, consider all of its unvisited neighbors and calculate their distances by adding the current distance of the ...
