本系列介绍几种序列对齐方法,包括Dynamic time warping (DTW),Smith–Waterman algorithm,Cross-recurrence plot Dynamic time warping (DTW) is a well-known technique to find an optimal alignment between two given (time-dependent) sequences under certain restrictions. ——Meinard Muller的《Information Retriev...
Sequence Alignment Using Nature-Inspired Metaheuristic Algorithms However, Needleman-Wunsch algorithm has some lack when the length of the sequence which is aligned is big enough. Because of that, sequence alignment is solved by metaheuristic algorithms. In the present, there are a lot of new ......
Smith-Waterman is a local alignment technique that uses a recursive algorithm and can use alternative gap penalties (such as affine). Smith-Waterman’s algorithm is an extension of Longest Common Substring (LCS) problem and can be generalized to solve both local and global alignment. Note: ...
Needleman-Wusch algorithm与longest common subsequence (LCS)很相似,最大差别在于它给LCS中增、减、替换等操作赋予了不同的负权值,甚至不同的匹配对(a,a),(b,b)也有不同的正权值。可以这么说,Needleman-Wusch algorithm是改进的LCS算法。主要解决如下谁最优的问题: ...

In this article we propose a Fast Optimal Global Sequence Alignment Algorithm, FOGSAA, which aligns a pair of nucleotide/protein sequences faster than any optimal global alignment method including the widely used Needleman-Wunsch (NW) algorithm. FOGSAA is applicable for all types of sequences, wi...
Especially for the sequences with sequence identity less than 15%, our method improves the alignment accuracy significantly. Moreover, we also showed that our algorithm works well together with a consistency-based progressive multiple alignment by modifying the TCoffee to use our measure./p p...
