What is Bellman Ford? The Bellman-Ford algorithm computes shortest paths from a single source vertex to every other vertex in a weighted (,and in our case, directed) graph. Unlike the more popular Djikstra's algorithm, this algorithm is capable of finding shortest paths even in graphs with negative edge weights (but no negative weight cycles).
We will start with the O(V×E) Bellman-Ford algorithm first as it is the most versatile (but also the slowest) SSSP algorithm. We will then discuss 5 (FIVE) other algorithms (including two variants of Dijkstra's algorithm) that solve special-cases of SSSP problem in a much faster manner.

The Bellman-Ford algorithm is best suited to find the shortest paths in a directed graph, with one or more negative edge weights, from the source vertex to all other vertices. It does so by repeatedly checking all the edges in the graph for shorter paths, as many times as there are vertices in the graph (minus 1).
