- Make case-swaps half the cost of any other edit - Refactor Levenshtein code to not use memory allocator, and to bail early on no match. - Add comments to Levenshtein distance code - Add test cases for Levenshtein distance behind a debug macro - Set threshold to `(name_size + item_size + 3) * MOVE_COST / 6`. - Reasoning: similar to `difflib.SequenceMatcher.ratio()` >= 2/3: ``` "Multiset Jaccard similarity" >= 2/3 matching letters / total letters >= 2/3 (name_size - distance + item_size - distance) / (name_size + item_size) >= 2/3 1 - (2*distance) / (name_size + item_size) >= 2/3 1/3 >= (2*distance) / (name_size + item_size) (name_size + item_size) / 6 >= distance With rounding: (name_size + item_size + 3) // 6 >= distance ``` Co-authored-by: Pablo Galindo <pablogsal@gmail.com> |
