WebDijkstra's algorithm works slightly differently. It treats all edges the same, so that when it considers the edges leaving a vertex, it processes the adjacent vertices together, and in no particular order.For example, when Dijkstra's algorithm processes the edges leaving vertex s, it declares that y.dist = 4, t.dist = 6, and y.pred and t.pred are both s—so far … arti enggalWebMay 20, 2024 · The algorithm works by building a set of nodes that have a minimum distance from the source.
