WebDijkstra algorithm is a greedy algorithm. It finds a shortest-path tree for a weighted undirected graph. This means it finds the shortest paths between nodes in a graph, which may represent, for example, road networks. For a given source node in the graph, the algorithm finds the shortest path between the source node and every other node.
