Rethink the Dijkstra algorithm -- Let's go deeper

Правка en1, от CristianoPenaldo, 2022-10-10 06:49:27

For a long time I think the Dijkstra only has two usages:

(1) Calculate the distance between the vertices when the weights of edges are non-negative.

(2) Given a path $$$p = x_1x_2...x_n$$$

dijkstra, graph theory, functional programming
