From: Island method for estimating the statistical significance of profile-profile alignment scores
Speed-up vs. the difference in the estimates of λ. The speed advantage of the island method and the deviation of the island estimates of λ from the parameters obtained by the direct method. The island scores and the optimal alignment scores were collected from 10,000 comparisons between the shuffles of random profiles. The results are averaged over 100 pairs of random profiles.
