"WebYour task is to find the minimum shortest path between any pair of nodes in the graph. As the weight of the edges can be negative, the path is allowed to visit the same node multiple times. Formally, let F(u, v) be the shortest path between the two nodes u and v, find the minimum F(u, v) over all pairs (u, v) (1 ≤ u, v ≤ N) (u ≠ v). " - Optimal path codeforces

WebThe difference will include a path from s to t and some cycles. A cycle cannot cause a decrease in cost, otherwise we can find a better flow with value k. So it's optimal to just augment a path. In particular, an optimal augmenting path must be the shortest with our given weighting.
