WebFeb 23, 2024 · Data Structure Analysis of Algorithms Algorithms. Instead of giving a single shortest path, Yen’s k-shortest path algorithm gives k shortest paths so that we can get the second shortest path and the third shortest path and so on. Let us consider a scenario that we have to travel from place A to place B and there are multiple routes available ... WebIt allows some of the edge weights to be negative numbers, but no negative-weight cycles may exist. It works by using the Bellman–Ford algorithm to compute a transformation of the input graph that removes all negative weights, allowing Dijkstra's algorithm to be used on the transformed graph.
