data: seq_a, seq_b factors: exact Levenshtein distance by dynamic programming over the two sequences (47 and 47 bases; insertion, deletion and substitution cost 1): 3 (0.9), cross-check: the distance is the same read from either sequence (3) and lies inside the stated range (0.1) rejected: the snapshot's naive value (5): a heuristic, not the distance; Hamming distance (substitutions only): the puzzle also counts insertions and deletions, and here it would read 33 |
