WebIn computer science, a disjoint-set data structure, also called a union–find data structure or merge–find set, is a data structure that stores a collection of disjoint (non-overlapping) sets. Equivalently, it stores a partition of a set into disjoint subsets. It provides operations for adding new sets, merging sets (replacing them by their ... WebDisjoint union; Type: Set operation: Field: Set theory: Statement: The disjoint union of the sets A and B is the set formed from the elements of A and B labelled (indexed) with the name of the set from which they come.

WebIn graph theory, a component of an undirected graph is a connected subgraph that is not part of any larger connected subgraph. The components of any graph partition its vertices into disjoint sets, and are the induced subgraphs of those sets.

A partition of set A is a set of one or more nonempty subsets of A: A1, A2, A3, ⋯, such that every element of A is in exactly one set. Symbolically, A1 ∪ A2 ∪ A3 ∪ ⋯ = A. If i ≠ j then Ai ∩ Aj = ∅. The subsets in a partition are often referred to as blocks.
