set-utilities
High performance set theory - functional utilities which operate on arbitrary input sets.
union-find
A union-find data structure for maintaining disjoint sets.
relationset
Compare two sets (array of items) and get relationships between them (Disjoint | Intersecting | Subset | Superset | Equal)
merge-find
Implementation of Disjoint-set data structure algorithm (also called a union–find data structure or merge–find set).
