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...

A fast union-find algorithm for the computation of these operators is presented in this paper. The new algorithm has a worst case time complexity of O ( N log N ) where N is the image size, as opposed to O ( N 2 log N ) for the existing algorithm. Memory requirements are O ( N...

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...
Space Complexity:O(m+n), the space needed for the map (where m and n are the sizes of the given lists). So, in this article, we have seen a detailed approach and algorithm for the union and intersection of two linked lists .This is an easy problem with many approaches. Knowing this...

On the single-operation worst-case time complexity of the disjoint set union problem. We give an algorithm for the disjoint set union problem, within the class of algorithms defined by Tarjan, which has O(log n/loglog n) single-operation tim... N Blum - Springer-Verlag 被引量: 130发表:...
