本文简要介绍了随机微分方程的Ito-Taylor展开式。应用有色根树理论推导了强阶1.0隐式随机龙格-库塔方法(SRK)。提出了两种完全隐式的方案并讨论了它们的稳定性。数值报告说明了更好的数值行为。
In this paper, the Ito-Taylor expansion of stochastic differential equation is briefly introduced. The colored rooted tree theory is applied to derive strong order 1.0 implicit stochastic Runge-Kutta method(SRK). Two fully implicit schemes are presented and their stability qualities are discussed. And the numerical report illustrates the better numerical behavior.
