Discrete Approximations and Optimality Conditions for Controlled Free-Time Sweeping Processes

open access: yesApplied Mathematics and Optimization
The paper is devoted to the study of a new class of optimal control problems governed by discontinuous constrained differential inclusions of the sweeping type with involving the duration of the dynamic process into optimization. We develop a novel version of the method of discrete approximations of its own qualitative and numerical values with ...

Residual-based a posteriori error estimates for the hp version of the finite element discretization of the elliptic Robin boundary control problem

open access: yesResults in Applied Mathematics, 2022
Optimal control problems governed by partial differential equations have become a very active and successful research area. So, in this paper, we analyzed a priori and a posteriori error estimates for the hpfinite element discretization of elliptic Robin

A Novel Technique to Control the Accuracy of a Nonlinear Fractional Order Model of COVID-19: Application of the CESTAC Method and the CADNA Library

open access: yesMathematics, 2021
In this paper, a nonlinear fractional order model of COVID-19 is approximated. For this aim, at first we apply the Caputo–Fabrizio fractional derivative to model the usual form of the phenomenon.

An approximation to discrete optimal feedback controls [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
We study discrete solutions of nonlinear optimal control problems. By value functions, we construct difference equations to approximate the optimal control on each interval of “small” time. We aim to find a discrete optimal feedback control. An algorithm is proposed for computing the solution of the optimal control problem.

A discrete orthogonal polynomials approach for fractional optimal control problems with time delay [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2019
An efficient direct and numerical method has been proposed to approximate a solution of time-delay fractional optimal control problems. First, a class of discrete orthogonal polynomials, called Hahn polynomials, has been introduced and their properties ...

Newton’s method for reinforcement learning and model predictive control

open access: yesResults in Control and Optimization, 2022
The purpose of this paper is to propose and develop a new conceptual framework for approximate Dynamic Programming (DP) and Reinforcement Learning (RL). This framework centers around two algorithms, which are designed largely independently of each other ...
