Detecting similarities of multiple genome sequences is one of the most important topics in genome informatics. For the purpose of finding such similarities, an alignment with the highest score with respect to some similarity criterion is provided as an output. However, the alignment with the best score is not necessarily the most significant alignment of the sequences from the viewpoint of biology. In this respect, providing suboptimal alignments is very useful.
