摘要
针对抛物型初边值问题提出了一种新的方法——RK-DMG法.这个方法有机地结合了Runge-Kutta法和剩余校正多层网络方法.从而具有速度快、精度高等优点.它不仅适于求解线性抛物型问题,而且适于求解非线性抛物型问题.
A new method-the RK-DMG method for solving the initial and boundary value problems of the parabolic type is proposed. The method is theoretically proved to be fast speed and high precision. Furthermore,it easily practises on parallel computers and is also applied to initial boundary problems of non-linear parabolic type.
