Step by step results of the Floyd-Warshall algorithm execution for k = 1, i = 0 and j = 2,4 on the graph illustrated on Picture 2. We have found two paths: a new path (0 ⭢ 1 ⭢ 2) and a shortcut (0 ⭢ 1 ⭢ 4).Both go through vertex 1.If we don’t store this information (the fact we got to 2 and 4 through 1) somewhere right now it will be lost …

The Floyd–Warshall algorithm is an example of dynamic programming, and was published in its currently recognized form by Robert Floyd in 1962. However, it is essentially the same as algorithms previously published by Bernard Roy in 1959 and also by Stephen Warshall in 1962 for finding the transitive closure of a …

The graph has a negative cycle if at the end of the algorithm, the distance from a vertex v to itself is negative. This algorithm has been simultaneously published in articles by Robert Floyd and Stephen Warshall in 1962.
