[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.

Generally, programmatic buying is similar to programmatic stock trading insofar as buying happens as the result of a computational proxy bidding on behalf of human masters. An example of HPB would be to bid a fixed amount of $6.00 on any visitor that's been on an advertiser's website in the last 30 days.
