Numerical Solutions for Optimal Control of Stochastic Kolmogorov Systems

Numerical Solutions of Stochastic Control Problems for Regime-switching Systems

In this paper, we develop approximation methods for solving stochastic control problems. The systems under consideration involve regime switching, modulated by a continuous-time Markov chain. Using Markov chain approximation techniques, we construct discrete-time Markov chains having two components. In addition to convergence of the procedure, numerical experiments and remarks on controlled var...

Numerical method for solving optimal control problem of the linear differential systems with inequality constraints

In this paper, an efficient method for solving optimal control problems of the linear differential systems with inequality constraint is proposed. By using new adjustment of hat basis functions and their operational matrices of integration, optimal control problem is reduced to an optimization problem. Also, the error analysis of the proposed method is nvestigated and it is proved that the orde...

Quantitative Determination Of Optimal Fiscal And Monetary Policies: A Stochastic Optimal Control Analysis For Iran

Coexistence and extinction for stochastic Kolmogorov systems

In recent years there has been a growing interest in the study of the dynamics of stochastic populations. A key question in population biology is to understand the conditions under which populations coexist or go extinct. Theoretical and empirical studies have shown that coexistence can be facilitated or negated by both biotic interactions and environmental fluctuations. We study the dynamics o...

Numerical Solution of Optimal Control of Time-varying Singular Systems via Operational Matrices

In this paper, a numerical method for solving the constrained optimal control of time-varying singular systems with quadratic performance index is presented. Presented method is based on Bernste in polynomials. Operational matrices of integration, differentiation and product are introduced and utilized to reduce the optimal control of time-varying singular problems to the solution of algebraic ...
