Meshfree Approximation for Stochastic Optimal Control Problems

Hui Sun, Feng Bao

摘要:

本文利用无网格逼近方法实现空间维逼近,研究了求解一类随机控制问题的梯度投影法。我们的主要贡献是将现有的梯度投影法推广到中等高维空间。移动最小二乘法和一般径向基函数插值方法作为展示方法介绍了我们的计算框架,并提供严格的数值分析,以证明我们的无网格逼近方法的收敛性。我们还提出了一些数值实验来验证我们的方法的理论结果,并证明了性能无网格逼近在解决随机最优控制问题。

英文摘要:

In this work, we study the gradient projection method for solving a class of stochastic control problems by using a mesh free approximation approach to implement spatial dimension approximation. Our main contribution is to extend the existing gradient projection method to moderate high-dimensional space. The moving least square method and the general radial basis function interpolation method are introduced as showcase methods to demonstrate our computational framework, and rigorous numerical analysis is provided to prove the convergence of our meshfree approximation approach. We also present several numerical experiments to validate the theoretical results of our approach and demonstrate the performance meshfree approximation in solving stochastic optimal control problems.
