## For five taxon unrooted trees there are fifteen topologies and not all are connected.

In dynamic programming, we break down a complex problem into a series of simpler steps that have a nested structure. Jul 08, pruner: Implementing the Felsenstein's Tree Pruning algorithm. This C++ template library provides classes to implement Felsenstein tree-pruning algorithm for efficiently computing likelihood functions on phylogenies.

In statistical genetics, Felsenstein's tree-pruning algorithm (or Felsenstein's tree-peeling algorithm), attributed to Joseph Felsenstein, is an algorithm for computing the likelihood of an evolutionary tree from nucleic acid sequence data. Felsenstein’s pruning algorithm was important in the history of phylogenetics because it allowed scientists to efficiently calculate the likelihoods of comparative data given a tree and a model.

One can then maximize that likelihood by changing model parameters (and perhaps also the topology and branch lengths of the tree; see Felsenstein ). Dec 14, Felsenstein’s pruning algorithm allows one to calculate the probability of any particular data pattern arising on a phylogeny given a model of character evolution. Here we present a similar dynamic programming algorithm. Our algorithm treats the tree and model as bushhaul.bar by: 3.
