Time complexity: So, the approach above cannot decrease the union operation time complexity, rather, it increases the find operation time complexity. If we have a closer look, we can find the reason why quick-union approach is not performing well is because the height of the tree could be v...
The algorithm has a time complexity of O(alpha(N)), where N is the number of elements in the set and alpha(N) is the inverse Ackermann function, which grows very slowly and can be considered constant for most practical purposes. C++ Implementation of Union-Find Algorithm Below is the ...
So, the approach above cannot decrease the union operation time complexity, rather, it increases the find operation time complexity. If we have a closer look, we can find the reason why quick-union approach is not performing well is because the height of the tree could be very tall. So, ...
The time complexity bounds of the very efficient operations on union-find structures transfer to our monitoring algorithm: the execution time of a single monitoring step is guaranteed logarithmic in the number of observed objects. The amortised time is bound by an inverse of Ackermann's function. ...

This paper presents a linear-time algorithm for the special case of the disjoint set union problem in which the structure of the unions (defined by a “union tree”) is known in advance. The algorithm executes an intermixed sequence of m union and find operations on n elements in O(m+n...
The time complexity of the Union and Find operation isO(n)in the worst case, wherenis the total number of vertices in the graph. Please refer to the implementation of Find and Union discussed in theoriginal postfor improving the overall time complexity of the algorithm. ...
