This paper mainly studies the algorithm analysis of two types of stochastic differential equations, namely stochastic ordinary differential equations and stochastic partial differential equations. For stochastic ordinary differential equations, we mainly consider classic Euler-Maruyama method and modern improved methods, such as Milstein method, Taylor method, etc., and compare their accuracy and computational complexity. For stochastic partial differential equations, we mainly consider algorithms based on finite element method and finite difference method, and compare and analyze them. Finally, we will summarize and look forward to the algorithm research of the two types of stochastic differential equations.Keywords: stochastic differential equation; stochastic ordinary differential equation; stochastic partial differential equation; computational method; accuracy analysis; complexity analysis.
