基于最优化方法的偏微分方程求解器

Partial differential equation solver based on optimization methods

Alexander Hvatov

摘要:

求解偏微分方程(PDE)的数值解,如果应用于正确的问题,可以得到一个收敛于解的离散场。然而,数值方法通常都有方程的限制类,并在此基础上证明了收敛性。只有少数“廉价而肮脏”的数值方法以较低的逼近阶价格收敛于广泛的一类方程。在这篇文章中,我们提出了一种方法,使用优化算法来获得一个解决方案,可以用作广泛的方程类的初始猜测。

英文摘要:

The numerical solution methods for partial differential equation (PDE) solution allow obtaining a discrete field that converges towards the solution if the method is applied to the correct problem. Nevertheless, the numerical methods usually have the restricted class of the equations, on which the convergence is proved. Only a small amount of "cheap and dirty" numerical methods converge on a wide class of equations with the lower approximation order price. In the article, we present a method that uses an optimization algorithm to obtain a solution that could be used as the initial guess for the wide class of equations.
