构造了求解Stratonovich随机微分方程的三级半隐式随机龙格库塔方法,给出了其两种数值格式,并讨论了方法的数值稳定性和计算精度.与同阶方法相比,所给方法具有更优越的稳定性和计算精度.
We discussed three-stage semi-implicit stochastic Runge-Kutta methods for Stratonovich stochastic differential equations. The mean-square stability properties of the methods were examited. The stability properties and numerical results show the effectiveness of these methods in the pathwise approximation of stochastic differential equations.
