e ends of the currently picked edge belong to different subtrees, these subtrees are combined, and the edge is added to the answer. after iterating through all the edges, all the vertices will belong to the same sub-tree, and we will get the answer. minimum spanning tree advanced algorithm: dsu algorithms and data structures course the complexity of described algorithm is in the simple version of the kruskal algorithm, we sort all the edges of the graph in non-decreasing order of weights. then put each vertex in its own tree (i.e. its set) via calls to the function - it will take a total of . we iterate through all the edges (in sorted order) and for each edge determine whether the ends belong to different trees (with two calls in each). finally, we need to perform the union of the two trees (sets), for which the dsu function will …
