The speed up effect in parallel computation is shown in Figure 1.6. We also carried out estimation of branch lengths in 10 MRF family genes (Figure 1.7). In many cases, branch lengths are greater in the maximum likelihood method than in the neighbor joining method. Especially, in the case of internal nodes, the differences are obvious.
