Calculate the weight of the minimum spanning tree in this graph. Input The first line containsnn(1≤n≤2×1051≤n≤2×105) — the number of vertices in the graph. The second line containsnn integersa1,a2,⋯,an(
2.2. The Algorithm The central idea of the algorithm is to start with a bunch of trees with each vertex representing an isolated tree. Then, we need to keep adding edges to reduce the number of isolated trees until we have a single connected tree. Let’s see this in steps with an exam...
[Tutorial] Boruvka's Algorithm Difference between en2 and en3, changed 213 character(s) Hi everyone, ↵ ↵ Recently I discovered Boruvka's Algorithm and I think this algorithm is really interesting. So I made a video lecture on this algorithm where I cover 2 problems related to it (1 ...
I think your solution must be interesting, could you please explain how would you approach Boruvka's algorithm without DSU?
方法：将边都添加进最小优先权队列中，每次从中取出最小的边，检查会不会与已经选出的边构成环（使用...
算法的基本思想是每次需要寻找距离最小的一个结点(与Dijkstra’s Algorithm相似),以及新的边来更新其它结点的距离。在寻找距离最小点的过程中,可以暴力查找,也可以采用堆维护进行优化。在使用二叉堆优化的加持下,复杂度 。相比于 , 更适用于稠密图。 对于最小生成树,我们一般将这类问题进行分类,对于稀松图选择 ...
