# modify the Bellman-Ford algorithm

Not what you're looking for?

Show how to modify the Bellman-Ford algorithm to find and print a negative weight cycle (reachable from the source, s) in a weighted directed graph G if one exists. If there is no negative weight cycle, your algorithm should print out "no negative weight cycle reachable from". If there is a negative weight cycle reachable from the source vertex, your algorithm should display one such cycle.

##### Solution Summary

This solution suggests ideas to modify the Bellman-Ford algorithm are included.
