Defination 给一个无向连通图,生成一颗边权和最小的树 Algorithm Prime: 看作两个集合,每次找出集合间最小的边选入,把对应点选入。 该算法中,“集合”和“讨论集合之间的边”的思路很妙,在删边最短路和删点最短路中都有运用。 kruskal:sort边,从小到大加入。 Application 1.martix tree 定理 (咕...猜...

Kruskal 克鲁斯克尔算法(Kruskal's algorithm)是图论中一种寻找最小生成树的贪心算法。 算法流程 初始化:V_{new}=V,E_{new}=\{\},每个点自成一个连通分量S_i=i,i\in V。 循环以下步骤至<V_{new},E_{new}>所有点都连通: 选取一条边e=\min\limits_{(u,v)}\{W(e)|e=(u,v)\and u,v\in...
5、算法选择： Prim算法适用于边稠密的图，而Kruskal算法适用于边稀疏的图。How to implement graph's minimum spanning tree algorithms (such as Prim's or Kruskal's algorithm) in Java:Characteristics of Prim's Algorithm: It starts from a single vertex and gradually grows a minimum spanning tree that...
