Can Dijkstra’s Algorithm Handle Negative Edges Cycles? shortest-path problem Which algorithm does not work with negative edges? As 3 is less than 5, but Dijkstra’s algorithm gives the incorrect answer as 5, which is not the shortest distance. Therefore Dijkstra’s Algorithm fails for negative cases. Can we use Dijkstra’s algorithm to find the shortest paths

Can Bellman Ford Detect All Negative Weight Cycles?

Can Bellman Ford Detect All Negative Weight Cycles? 1. Bellman-Ford detects negative cycles, i.e. if there is a negative cycle reachable from the source s, then for some edge (u, v), dn-1(v) > dn-1(u) + w(u, v). 2. If the graph has no negative cycles, then the distance estimates on the last iteration are equal
