Visualizing reticulate evolution with planar split networks

Tuesday 21st June 2011 - 11:50 to 12:10
INI Seminar Room 1
Split networks have been developed as a tool to visualize collections of bipartions of a finite set, so called split systems. We present a new method that allows to compute drawings of split networks without crossing edges for a rich class of split systems that include as special cases compatible and circular split systems. In addition, we show that the drawings produced by our method are optimal in the sense that any drawing with less edges would necessarily miss out some of the information contained in the given split system.
