Web8 feb 2015 · The union-find algorithm is best suited for situations where the equivalence relationship is changing, i.e., there are "Union" operations which need to be performed on your set of partitions. Given a fixed undirected graph, you don't have the equivalence relationships changing at all - the edges are all fixed. WebThe only programming contests Web 2.0 platform.

We will store the sets in the form of trees: each tree will correspond to one set.And the root of the tree will be the representative/leader of the set. In the following image you can see the representation of such trees. In the beginning, every element starts as a single set, therefore each vertex is its own … Visualizza altro In this section we consider several applications of the data structure, both the trivial uses and some improvements to the data structure.
