An Approximate Method for Solving Optimal Control Problems for Discrete Systems Based on Local Approximation of an Attainability Set

An optimal control problem for discrete systems is considered.A method of successive improvements along with its modernization based on the expansion of the main structures of the core algorithm about the parameter is suggested.The idea of the method is based on local approximation of attainability set, which is described by the zeros of the Bellma

Species delimitation and phylogeography of Aphonopelma hentzi (Araneae, Mygalomorphae, Theraphosidae): cryptic diversity in North American tarantulas.

BackgroundThe primary objective of this study is to reconstruct the phylogeny of the hentzi species group and sister species in the North American tarantula genus, Aphonopelma, using a set of mitochondrial DNA markers that include the animal "barcoding gene".An mtDNA genealogy is used to consider questions regarding species boundary delimitation an
