(data structure)
Definition: A variant of a trie in which leaf nodes are buckets which hold up to k strings. Usually implies fixed sized buckets.
Generalization (I am a kind of ...)
trie.
Specialization (... is a kind of me.)
elastic-bucket trie.
Note: Combining terminal strings can greatly shorten branches. For instance, "extraordinarily", "extraordinariness", and "extraordinary" can be stored in one bucket at the end of a short branch distinguishing them from extran... and extrap... rather than a long branch for the common substring ...ordinar...
The name comes from reTRIEval and is pronounced, "tree." See the historical note at trie.
