Optimal control for a chemotaxis–haptotaxis model in two space dimensions

open access: yesBoundary Value Problems, 2022
This paper deals with a chemotaxis–haptotaxis model which described the process of cancer invasion on the macroscopic scale. We first explore the global-in-time existence and uniqueness of a strong solution.

Feedback Minimum Principle for Quasi-Optimal Processes of Terminally-Constrained Control Problems

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
In a series of previous works, we derived nonlocal necessary optimality conditions for free-endpoint problems. These conditions strengthen the Maximum Principle and are unified under the name “feedback minimum principle”.

A global optimization paradigm based on change of measures [PDF]

open access: yesRoyal Society Open Science, 2015
A global optimization framework, COMBEO (Change Of Measure Based Evolutionary Optimization), is proposed. An important aspect in the development is a set of derivative-free additive directional terms, obtainable through a change of measures en route to ...

Global optimization of multivariable functions satisfying the Vanderbei condition [PDF]

open access: yesJournal of Applied Mathematics and Computing, 2021
We propose two algorithms for solving global optimization problems on a hyperrectangle with an objective function satisfying the Vanderbei condition (this function is also called an $\varepsilon$-Lipschitz continuous function). The algorithms belong to the class of non-uniform cover-ings methods.

Optimization of the standard genetic code according to three codon positions using an evolutionary algorithm. [PDF]

open access: yesPLoS ONE, 2018
Many biological systems are typically examined from the point of view of adaptation to certain conditions or requirements. One such system is the standard genetic code (SGC), which generally minimizes the cost of amino acid replacements resulting from ...

A new filter QP-free method for the nonlinear inequality constrained optimization problem

open access: yesJournal of Inequalities and Applications, 2018
In this paper, a filter QP-free infeasible method with nonmonotone line search is proposed for minimizing a smooth optimization problem with smooth inequality constraints.

A Computational Method for Solving $N$-Person Game

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
The nonzero sum $n$-person game has been considered. It is well known that the game can be reduced to a global optimization problem [5; 7; 14]. By extending Mills’ result [5], we derive global optimality conditions for a Nash equilibrium.

Second Order Krotov Method for Discrete-Continuous Systems

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
In the late 1960s and early 1970s, a new class of problems appeared in the theory of optimal control. It was determined that the structure of a number of systems or processes is not homogeneous and can change over time. Therefore, new mathematical models
