Application of Controlled Perturbation Method for Real-time Modification of Neuro Controllers / Dziuba D.O., Chernodub A.M. // Mathematical Machines and Systems. - 2011. - N 1. - P. 20 - 28.
New method for training neural networks to control dynamic objects is proposed. The method is based on estimation of local values of Jacobian of object's position on control signal by introducing a small perturbation in applied control. The method does not require any a priori information about controlled object and may be applied for adaptive control over objects of different nature. Experiments on application of the proposed method for recurrent neural networks training within control systems of different objects show advantages of such neuro control versus standard PID-control.

Biogenetic law of Haeckel and its role in revealing the mechanism of retransmission of natural laws during the process of creation and evolution of computer techniques. Рart 3 / Briukhovych Ye.I. // Mathematical Machines and Systems. - 2011. - N 1. - P. 147 - 153.
An answer has been obtained on how a human creates and evolves computer techniques by natural laws. The answer is in the action mechanism of the known Central Dogma of Molecular Biology (CDMB), which underlies the Haeckel's biogenetic law, and which became a new substantiation of correctness of assertions of this law. According to the law, a short and quick repetition (recapitulation) of the most important stages of the evolution of species (phylogenesis) is taking place by individual development of a person (ontogenesis). The recapitulation is determined by reproducing from RNA a copy of the genetic information, contained in DNA, without destroying the original, as a result of which a sequential lamination (accumulation) of genetic information occurs in DNA during the whole phylogenesis of species. A conclusion has been made that a human, creating and evolving the computer techniques, not realizing this, recapitulates phylogenesis from Homo sapiens into ontogenesis of Computer sapiens.
