Cophenetic metrics for phylogenetic trees, after Sokal
Proofs of Propositions 1–4 Proof of Proposition 1 By Lemma 1, it is enough to prove that the minimum non-zero value ofD0 is 1, and that all pairs T, T ′ ∈ UT n such that D0(T, T ′) = 1 also satisfy that Dp(T, T ′) = 1 for every p > 1. As we have seen in Example 2, if we contract a pendant arc in a tree T , we obtain a new tree T ′ such that Dp(T, T ′) = 1, for every p ∈ {0}∪ [1,∞[, and this is ...
متن کاملRisking Connection Across Difference: Reply to Sokal and Smith
At the time I wrote my original review (Schultz 2010) of the books by Sokal (2008), Boghossian (2006), and Smith (2006), I did not know that I would have the opportunity to reply to their responses to my review. Nevertheless, I value the occasion this offers to correct errors and respond to their commentary. Let me say, first of all, that Alan Sokal is quite correct in pointing out that the cit...
متن کاملThe Latest on the Sokal Affair: Beyond Three Extremisms
After a short summary of the Sokal Affair and of the point of view of Steven Weinberg, we discuss certain aspects of the scientist ideology present in the last book of Alan Sokal Pseudoscience and Postmodernism: Antagonists or Fellow-Travelers?, published in France. The danger of the three extremisms present in our time relativist extremism, scientist extremism and its mirror-image, the religio...
متن کاملConstructing Camin-Sokal Phylogenies Via Answer Set Programming
The problem of constructing a most parsimonious phylogenetic tree from species data, the maximum parsimony problem, is central to phylogenetics and has diverse applications elsewhere. Most natural variations of the problem, including the cladistic Camin-Sokal (CCS) version studied here, are NP-complete. The usual approach to solving these problems is branch-and-bound (BNB); packages using BNB o...
متن کاملRobert Insall
Robert Insall was born in London in 1965, into a family of architects, musicians and historians. To their great surprise, he was obviously scientifically inclined from an early age. He did a B.A. at Cambridge University, then stuck around in Cambridge for a Ph.D., where he got interested in Dictyostelium, followed by a postdoc in Johns Hopkins, where he got interested in chemotaxis and cell mov...
