关于算法的正确性证明网上都有证明,这里就不再赘述。 1//inf为路径权上界,maxn为图的临接矩阵的点数2//vis是记录是否访问过,cost[i]记录到达第i个节点的最小代价3constintinf=0x7fffffff,maxn=101;4intG[maxn][maxn],vis[maxn],cost[maxn],n;5//len为MST长度6intprim(){7memset(vis,0,sizeof(...
Minimum Spanning Tree Algorithm Given a list of Connections, which is the Connection class (the city name at both ends of the edge and a cost between them), find some edges, connect all the cities and spend the least amount. Return the connects if can connect all the cities, otherwise re...

spanning tree不一定唯一 ∵ 可能會有 2 個或 2 個以上的邊具有相同的cost 若一連通無向圖G,其各邊cost皆不相同,則會具有唯一的min. spanning tree 在min. spanning tree中,各頂點之間距離並非是shortest path Ex: 之前兩個演算法所用的例子,其中頂點對 (V2, V4) 的最短距離應為6,但所導出的兩個MST,...
In the end, we end up with a minimum spanning tree with total cost 11 ( = 1 + 2 + 3 + 5). Implementation: #include <iostream> #include <vector> #include <utility> #include <algorithm> using namespace std; const int MAX = 1e4 + 5; int id[MAX], nodes, edges; pair <...

We consider the problem of cost allocation among users of a minimum cost spanning tree network. It is formulated as a cooperative game in characteristic function form, referred to as a minimum cost spanning tree (m.c.s.t.) game. We show that the core of a m.c.s.t. game is never ...
Prim's Algorithm Intuition In 1957 Robert C. Prim designed (or rather, redesigned) a sequence of steps to find a graph's Minimum Spanning Tree using path weights. The algorithm's steps are these: Select a random node. Choose the path with theminimum weightconnected to thechos...
