Inferring phylogenetic networks by the maximum parsimony criterion: a case study.
Horizontal gene transfer (HGT) may result in genes whose evolutionary histories disagree with each other, as well as with the species tree. In this case, reconciling the species and gene trees results in a network of relationships, known as the "phylogenetic network" of the set of species. A phylogenetic network that incorporates HGT consists of an underlying species tree that captures vertical...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Surprising properties of Maximum Parsimony on phylogenetic networks
Phylogenetic inference aims at reconstructing the evolutionary relationships of different species given some data (e.g. DNA, RNA or proteins). Traditionally, the relationships between species were assumed to be treelike, so the most frequently used phylogenetic inference methods like Maximum Parsimony were originally introduced to reconstruct phylogenetic trees. However, it has been well-known ...
متن کاملMaximum Parsimony Phylogenetic Inference Using Simulated Annealing
The Maximum Parsimony (MP) problem aims at reconstructing a phylogenetic tree from DNA sequences while minimizing the total number of genetic transformations. In this paper we propose a carefully devised simulated annealing implementation, called SAMPARS (Simulated Annealing for Maximum PARSimony), for finding near-optimal solutions for the MP problem. Different possibilities for its key compon...
متن کاملOn Computing the Maximum Parsimony Score of a Phylogenetic Network
Phylogenetic networks are used to display the relationship of different species whose evolution is not treelike, which is the case, for instance, in the presence of hybridization events or horizontal gene transfers. Tree inference methods such as Maximum Parsimony need to be modified in order to be applicable to networks. In this paper, we discuss two different definitions of Maximum Parsimony ...
