The Floyd–Warshall algorithm finds all-pairs shortest paths in a directed, weighted graph which contains no negative-weight cycles. That is, unlike Dijkstra's algorithm, it is guaranteed to correctly compute shortest paths even when some edge weights are negative. (Note however that it is still...
The Floyd–Warshall algorithm finds the shortest paths (and distances) in a directed weighted graph with positive or negative edge weights.

Der Floyd-Warshall-Algorithmus überarbeitet iterativ die Pfadlängen zwischen allen Knotenpaaren(i, j), einschließlich woi = j. Zunächst die Größe des Pfades(i, i)ist Null. Ein Weg[i, k…i]kann dies nur verbessern, wenn er eine Länge kleiner Null hat, also einen negati...
