  1. Floyd-Warshall: Dynamic Programming Floyd-Warshall computes all pairs, but let us

    focus on 5 to 6. 62 / 71

  2. Floyd-Warshall: Dynamic Programming We start by considering only start(5) and

    dest(6) when k is 0. 63 / 71

  3. Floyd-Warshall: Dynamic Programming Then we also consider node 1 when

    k is 1. 64 / 71

  4. Floyd-Warshall: Dynamic Programming And node 2 when k is 2.

    65 / 71

  5. Floyd-Warshall: Dynamic Programming And node 3 when k is 3.....

    66 / 71

  6. Floyd-Warshall: Dynamic Programming And node 4 when k is 4....

    And so on. Note that I have just been filling in the answers for recursive calls But we actually need to compute those. 67 / 71

  7. Floyd-Warshall: Dynamic Programming Hmm it looks like some of those

    recursive calls will recompute the same thing... 68 / 71
