Property 3: If there are n elements overall, there can be at most n/2knodes of rank k. 如果一共有n个节点,那么rank 为k的连通支一共有n/2k个 对property2的解释:因为union的原则是让union后的树rank最小,所以union后的树至少是二叉树,也就是说除叶子节点外的节点至少有两个孩子。 对property3的...

Kruskal's Algorithm is an algorithm used to find the minimum spanning tree in graphical connectivity that provides the option to continue processing the least-weighted margins. In the Kruskal algorithm, ordering the weight of the ribs makes it easy to find the shortest path. This algorithm is ...
