[Show abstract] [Hide abstract] ABSTRACT: Computing the phylogenetic diversity of a set of species is an important part of many ecological case studies. More specifically, let \(\mathcal {T}\) be a phylogenetic tree, and let R be a subset of its leaves representing the species under study. Specialists in ecology want to evaluate a function \(f(\mathcal {T},R)\) (a phylogenetic measure) that quantifies the evolutionary distance between the elements in R.

In particular, businesses often force their customers through the companyâs selling processes instead of supporting the customerâs buying process. The buying process is the set of steps that a customer chooses to go through with the goal of satisfying a need. The selling process is the set of steps that a company uses to organize and optimize the way that it sells its products. Today, the differences between buying and selling processes are significant.
