All-pairs Shortest Path (APSP) algorithm finds the shortest path between any two nodes in a graph. It can be used to find the shortest path between two cities and other similar problems. There are many algorithms falling this APSP category. The one that we are discussing is the Floyd Warshall algorithm. The Floyd Warshall algorithm compares all possible paths through the graph between each pair of vertices. It does so by incrementally improving an estimate on the shortest path between two vertices, until the estimate is optimal.
