WebOct 13, 2024 · Dijkstra’s algorithm is very similar to Prim’s algorithm for minimum spanning tree. Like Prim’s MST, we generate a SPT (shortest path tree) with a given source as a root. We maintain two sets, one set contains vertices included in the shortest-path tree, other set includes vertices not yet included in the shortest-path tree. WebOct 12, 2024 · 前言. Dijkstra算法是最短路径算法中为人熟知的一种,是单起点全路径算法。. 该算法被称为是“贪心算法”的成功典范。. 本文接下来将尝试以最通俗的语言来介绍这个 …
