The Floyd-Warshall Algorithm, the AP and the TSP III
  We clarify the exposition of Phases 2 and 3a in "The Floyd-Warshall Algorithm, the AP and the TSP". We also improve and simplify theorem 3.6 . In line with clarifying the exposition, we change the matrices in examples 3.4 and 3.5 of "The Floyd-Warshall Algorithm, the AP and the TSP II".
