「最小生成樹(minimum spanning tree, MST)」探討的是如何透過移除最少權重(weight)的邊,使一原非屬「樹」的無向圖變成「樹」。 普林演算法(Prim’s algorithm) 以「貪婪演算法(greedy algorithm)」實現,透過一一拜訪節點、並比較與節點相連的邊,找到總權重最小、又不會形成環的組合。 若使用「斐波那契堆積(F...

2. Kruskal算法 此算法可以称为“加边法”,初始最小生成树边数为0,每迭代一次就选择一条满足条件的最小代价边,加入到最小生成树的边集合里。 (1)把图中的所有边按代价从小到大排序; (2)把图中的n个顶点看成独立的n棵树组成的森林; (3)按权值从小到大选择边,所选的边连接的两个顶点ui,viui,vi,应...
In this blog, we will be covering two major algorithms that are used to find the minimum spanning tree of a graph, naming Kruskal’s and Prim’s algorithms. We will also learn steps to find the minimum spanning tree algorithm with the help of one example. ...

There are several well known algorithms to solve this problem, the most well known being Prim's and Kruskal's. The challenge is very simple: implement as many of those algorithms as possible. You will be awarded one point for each exact algorithm that solve the minimum spanning tree problem...

对于N个顶点的连通网可以建立许多不同的生成树,每一棵生成树都可以是一个通信网。现在,要选择这样一颗生成树,也就是使总的耗费最少,这个问题就是构造连通网的的最小代价生成树的问题,即最小生成树问题。一颗生成树的代价就是树上各边的代价之和。
