data structures - Way to implement "Get all strings with Levenshtein distance less than X" -


i'm wondering whether there's efficient data structure perform "retrieve strings levenshtein distance less x".

few things i'm interested in:

  • explanation of algorithm.
  • is there existing implementation in existing database / programming langauge?
  • paper / article can refer to?

this nearest neighborer search in metric space levenshtein distance metric (or distance) function

a vp-tree 1 of ways of solving problem

this python vp-tree implementation working demo shows how vp-tree works run on word list provides interactive shell type word , returns words in list no more x distance word typed
