  • Properties of the triset metric for phylogenetic trees

    Publikacja

    - Rok 2012

    the following paper presents a new polynomial time metric for unrootedphylogenetic trees (based on weighted bipartite graphs and the method ofdetermining a minimum perfect matching) and its properties. also many its properties are presented.

  • Polynomial triset metric for unrooted phylogenetic trees

    the following paper presents a polynomial triset metric for unrooted phylogenetic trees (based on weighted bipartite graphs and the method of determining a minimum edge cover) and its basic characteristics. also a list of further directions of research and examples of the wider use of this metric is presented.

  • Critical Case Stochastic Phylogenetic Tree Model via the Laplace Transform

    Publikacja

    - Demonstratio Mathematica - Rok 2014

    Birth–and–death models are now a common mathematical tool to describe branching patterns observed in real–world phylogenetic trees. Liggett and Schinazi (2009) is one such example. The authors propose a simple birth–and–death model that is compatible with phylogenetic trees of both influenza and HIV, depending on the birth rate parameter. An interesting special case of this model is the critical case where the birth rate equals the...

  • Analyzing sets of phylogenetic trees using metrics

    Publikacja

    The reconstruction of evolutionary trees is one of the primary objectives in phylogenetics. Such a tree represents historical evolutionary relationships between different species or organisms. Tree comparisons are used for multiple purposes, from unveiling the history of species to deciphering evolutionary associations among organisms and geographical areas. In this paper, we describe a general method for comparing phylogenetictrees...

  • Comparing Phylogenetic Trees by Matching Nodes Using the Transfer Distance Between Partitions

    Publikacja

    - JOURNAL OF COMPUTATIONAL BIOLOGY - Rok 2017

    Ability to quantify dissimilarity of different phylogenetic trees describing the relationship between the same group of taxa is required in various types of phylogenetic studies. For example, such metrics are used to assess the quality of phylogeny construction methods, to define optimization criteria in supertree building algorithms, or to find horizontal gene transfer (HGT) events. Among the set of metrics described so far in...
