WebFor string comparison you have to use something different. 2 good choices here are Hamming and Levenshtein distance. In your particular case Levenshtein distance if more preferable (Hamming distance works only with the strings of same size). Now you can use one of existing clustering algorithms.

WebSpace complexity to compute the optimal string alignment for the Levenshtein edit distance. If we are given two strings of size n 1 and n 2, the standard Levenshtein edit distance computation is by a dynamic algorithm with time complexity O ( n 1 n 2) and space complexity O ( n 1 n 2). WebThe Needleman–Wunsch algorithm is still widely used for optimal global alignment, particularly when the quality of the global alignment is of the utmost importance. The algorithm assigns a score to every possible alignment, and the purpose of the algorithm is to find all possible alignments having the highest score. ...
