Dijkstra algorithm is used to solve

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 ... WebDijkstra’s algorithm can be used to solve all three presented shortest path problems so long as no negative edge weights exist in the graph. In Algorithm 2, we present the SSSP problem-solving variant of Dijkstra. In order to solve the APSP problem, we simply need to apply the same algorithm using every vertex in the graph as the source ...
