VGRAM: Improving Performance of Approximate Queries on String Collections Using Variable-Length Grams

Summary: VGRAM selects variable-length grams to speed up approximate string queries. It derives query grams from selected grams and links gram-set similarity to edit distance, enabling adoption by algorithms with minimal changes; experiments show speedups. (summarized by gpt-5-nano on Feb 09 2026)
