WebDijkstra’s Algorithm Given a graph G = (V;E) where edges have nonnegative lengths, and a source node s 2V, Dijkstra’s algorithm nds the shortest path from s to every other node. A standard implementation of Dijkstra’s algorithm is the following: For all v 2V, dv 1 ds 0 q:add(s) While q is not empty: v q:popFirst() WebDijkstra算法无法区分图中是否存在负边权重循环. 1。正边权重：-Dijkstra始终通过如果图形中的所有边权重均为正 2。负边权重和无-ve边权重循环：-Dijkstra始终通过，即使图中有一些边权重为负，但没有具有负边权重的循环。 [即不存在负边缘权重循环]
