Outline of Final Research Achievements

Despite the fact that RNA structural alignments have been studied for a long time, there is still a problem that the computational complexity is still large. For this reason, we cannot perform even a basic analysis of "comparing sequences" by exact methods for relatively long RNA sequences such as long non-coding RNAs and RNA viruses. In this research, we developed a fast and accurate method of calculating RNA structural alignments with consideration of complicated higher order structures such as pseudoknots by a novel algorithm based on maximizing the expected accuracy and the dual decomposition.
