Unverified使用 Levenshtein 自动机判断候选词是否接受的时间复杂度仅与候选词长度线性相关（O(n)），无需重新计算编辑距离矩阵65% similarUnverifiedEdit distance and character accuracy are insensitive to the 'position' and 'structure' of errors, and lack a clear 'pass/fail' semantic boundary64% similarUnverifiedThe A* algorithm builds on Dijkstra by introducing a heuristic function to estimate the remaining distance to the destination, significantly reducing the number of nodes expanded in point-to-point query scenarios.64% similarUnverified差分启发式的查询阶段计算 h(n, t) = 所有地标L中 |dist(n, L) - dist(t, L)| 的最大值，且该估计永远不会超过真实距离（可采纳性成立）63% similarUnverifiedOverall accuracy that mixes all distances will be dominated by the large number of easily recognizable nearby samples, thereby masking true performance deficiencies at greater distances.63% similar
