Rethink the Dijkstra algorithm -- Let's go deeper
For a long time I think the Dijkstra algorithm (dij) only has two usages:
(1) Calculate the distance between the vertices when the weights of edges are non-negative.
(2) (Minimax) Given a path $$$p = x_1x_2...x_n$$$, define $$$f(p) := \max_{i=1}^{n-1}d(x_i, x_{i+1})$$$. Given source vertex $$$s$$$ and target vertex $$$t$$$, dij is able to calculate $$$min \{f(p)|p \in s-t\,paths\}$$$
