WebJan 3, 2024 · Bellman Ford's algorithm is a shortest path finding algorithm for graphs that can have negative weights. Bellman ford's algorithm is also great for detecting negative weight cycles as the algorithm converges to an optimal solution in O (V*E) steps. If the resultant is not optimal, then graph contains a negative weight cycle. infinity = 1e10 def ...
