C ++中的dijkstra算法 [英] dijkstra algorithm in C++

问题描述

我有一个dijkstra算法，用于加权无向图.如何重新排列它以计算加权和有向图的最短路径?它在C ++中.参见 http://en.wikipedia.org/wiki/Dijkstra''s_algorithm [ 解决方案

You have more than enough information on this well-known algorithm to implement it in C++. See http://en.wikipedia.org/wiki/Dijkstra''s_algorithm[^].

Now, this article does not mention arc weights. You can easily modify the algorithm if you need to take it into account. Look at the distance calculation in the pseudocode (see dist, dist_between). When you calculate them, multiply each arc''s distance with its weight, that''s all you need.
