JO - Numerical Mathematics: Theory, Methods and Applications Such a large change occurs when the optimal solution is bang‐bang, 7, 32, 33, 37, that is, the optimal rate control at a well changes from its upper bound on one control step to zero on the next control step; see the first example of 37 for an illustration. A numerical example is included and sensitivity analyses with respect to the system parameters are examined to illustrate the importance and effectiveness of the proposed methodology. - 172.104.46.201. title = {Highly Accurate Numerical Schemes for Stochastic Optimal Control via FBSDEs}, This work is concerned with numerical schemes for stochastic optimal control problems (SOCPs) by means of forward backward stochastic differential equations (FBSDEs). SP - 296 Student Seminars. We study these problems within the game theoretic framework, and look for open-loop Nash equilibrium controls. Algebraic Topology II. This paper addresses a version of the linear quadratic control problem for mean-field stochastic differential equations with deterministic coefficients on time scales, which includes the discrete time and continuous time as special cases. A powerful and usable class of methods for numerically approximating the solutions to optimal stochastic control problems for diffusion, reflected diffusion, or jump-diffusion models is discussed. SN - 13 This is done by appealing to the geometric dynamic principle of Soner and Touzi [21]. © 2021 Springer Nature Switzerland AG. Publ. scholar, semantic AB -. Our numerical results show that our schemes are stable, accurate, and effective for solving stochastic optimal control problems. The auxiliary value function wis in general not smooth. The stochastic control problem (1.1) being non-standard, we rst need to establish a dynamic programming principle for optimal control under stochastic constraints. AU - Zhao , Weidong An example, motivated as an invest problem with uncertain cost, is provided, and the effectiveness of our method demonstrated. We facilitate the idea of solving two-point boundary value problems with spline functions in order to solve the resulting dynamic programming equation. (1967) Spline function approximations for solutions of ordinary differential equations. Math. Correspondence to Therefore, it is worth studying the near‐optimal control problems for such systems. Despite its popularity in solving optimal stopping problems, the application of the LSMC method to stochastic control problems is hampered by several challenges. journal = {Numerical Mathematics: Theory, Methods and Applications}, numerical optimization on the one hand, and system theory and numerical simulation on the other hand. It has numerous applications in science, engineering and operations research. In order to achieve the minimization of the infected population and the minimum cost of the control, we propose a related objective function to study the near‐optimal control problem for a stochastic SIRS epidemic model with imprecise parameters.
