(ii) merging two sets into a single set. Adisjoint set data structuremaintains a collection S fS 1, S 2, : : : , S kgof disjoint sets of objects, using the following three operations: Make Set(x): create a set whose only member is object x, where x is not in any sets yet.DisjointSet Data Structures We will analyze the running time of our data structures in terms of two parameters: , the number of MAKESET operations, and, the total number of MAKESET, UNION and FINDSET operations.

For instance, Kruskals minimum spanning tree algorithm relies on such a data structure to maintain the components of the intermediate spanning forest. Another application is maintaining the connected components of a data structure for disjoint sets pdf Disjoint set data structures have lots of applications.

Data Structures for Disjoint Sets Advanced Data Structures and Algorithms (CLRS, Chapter 21) James Worrell Oxford University Computing Laboratory, UK data structure for disjoint sets pdf DisjointSet Data Structures Supplemental reading in CLRS: Chapter 21 (21. 4 is optional) When implementing Kruskals algorithm in Lecture4, we built up a minimum spanning tree T by adding in one edge at a time. Along the way, we needed to keep track of the connected components of T; this was achieved using a disjointset data structure. 1 Data Structures Disjoint Sets (Union Find) Tzachi (Isaac) Rosen Also known as union find.
