How does Bellman-Ford algorithm handle negative weight cycles in a graph?

  • Adjusts the weights of edges in the negative cycle to make them positive
  • Continues the process, treating the graph as if there are no negative cycles
  • Ignores them
  • Terminates and outputs a negative cycle detected
Bellman-Ford algorithm detects negative weight cycles by observing that if there is a relaxation operation in the graph after performing V-1 iterations, then there is a negative weight cycle. It terminates and outputs the detection of a negative cycle in the graph.
