number of gaps and increase their significance. The gap penalty is a parameter that can be changed each time an alignment is run. By increasing or reducing the value of the gap penalties, the total number of gaps, their length, and their position in the sequence alignment may be controlled...
We present a cache-efficient parallel algorithm for the sequence alignment with gap penalty problem for shared-memory machines using multiway divide-and-conquer and not-in-place matrix transposition. Our rway divide-and-conquer algorithm, for a fixed natural number r≥2, performs Θ(n3) work, ...
Profile–profile alignment algorithms have proven powerful for recognizing remote homologs and generating alignments by effectively integrating sequence evolutionary information into scoring functions. In comparison to scoring function, the development of gap penalty functions has rarely been addressed in profile...
Since this optimization depends upon the specific edit distance criterion used to score a tree, our study considers the impact of the gap penalty ( in particular, affine versus simple) on the accuracy of the resultant alignment and tree that optimizes the treelength for that gap penalty ...
The correction was incorporated into a standard dynamic programming algorithm through a modification of the gap-penalty, but, unlike other approaches, this modification is not local and takes into consideration the overall alignment of the sequences. This implies that the algorithm cannot guarantee to...

Under their current scoring system, which uses a regular gap penalty, the alignment could also be written as in figure 2. This modification does not change the score, thus the two alignments are equivalent under this scoring system. For this new alignment, the C has been shifted one position...
End gap cost The penalty of gaps at the beginning or the end of the alignment. One of the advantages of the CLC Genomics Workbench alignment method is that it provides flexibility in the treatment of gaps at the ends of the sequences. There are three possibilities: Free end gaps Any ...
The essential difference of group-to-group sequence alignment from pairwise sequence alignment is the existence of gaps within each group of prealigned sequences. The gap opening penalty used in an affine gap cost disrupts the independence between adjacent columns, and hence calculating the optimal ...
