WebDijkstra is the shortest path algorithm.Dijkstra 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. WebIf we find the k shortest s paths in G ′, we also find the k shortest s – t paths in G. We can do that using a Dijkstra-like algorithm where we pop from the heap k times. Let's call it the k -pop algorithm. q = empty min heap push (d[s], s) on q repeat k times: (l, u) = pop q found a path of length l for each outgoing edge (u, v, w) from u ...
