Weball tree score. One iteration of the RAxML hill-climbing algorithm consists in performing LSRs on all subtrees for a given topology t and a fixed rearrangement dis-tance n. Thereafter, the branch lengths of the 20 best-scoring trees are thoroughly optimized. This procedure of conducting LSRs on all subtrees and then optimizing WebRAxML will refine the final BS tree under GAMMA and a more exhaustive algorithm. add new sequences to input tree (MP) performs just pure stepwise MP addition of new sequences …
