"WebDijkstra algorithm is used to find the shortest distance of all nodes from the given start node. It logically creates the shortest path tree from a single source node, by keep adding the nodes greedily such that at every point each node in the tree has a minimum distance from the given start node. Dijkstra algorithm is a greedy approach that ... " - Dijkstra algorithm cp algo
