Multiple sequence alignment (MSA) is a fundamental process in the studies for determination of evolutionary, structural and functional relationships of biological sequences or organisms. ...
There are various heuristic approaches comparing more than two sequences to generate MSA. However, each tool used for MSA is not suitable for every dataset. ...

With high computational costs of deterministic algorithms for sequence alignments, many works concentrate their efforts in the development of heuristic approaches to multiple sequence alignments. ...
The standard objective function implemented in the tool is the Weighted Sum of Pairs (WSP), which produces some distortions in the final alignments when sequences sets with low similarity are aligned. ...
Thus, as an alternative, we started to use heuristic techniques, especially for multiple sequence alignment. ...
