Evolutionary relationships between organisms are frequently derived as phylogenetic trees inferred from multiple sequence alignments (MSAs). The MSA parameter space is exponentially large, so tens of ...

All tree leaves have an outer layer called the epidermis, which can also be used in the identification process. This leaf "skin" always has a waxy cover called the cuticle and varies in thickness.

Given a set X of taxa, a phylogenetic X-tree T that is only partially resolved, and a collection of characters on X, we consider the problem of finding a resolution (refinement) of T that minimizes ...
