We begin with pervasive ultrametricity due to high dimensionality and/or spatial sparsity. How extent or degree of ultrametricity can be quantified leads us to the discussion of va...
Abstract. In this paper we present an algorithm that is able to progressively discover nodes of a Skype overlay P2P network. Most notably, super nodes in the network core. Starting...
A phylogenetic tree shows the evolutionary relationships among species. Internal nodes of the tree represent speciation events and leaf nodes correspond to species. A goal of phyl...
