摘要
讨论了随机人口方程解的数值方法,在方程的外部环境影响和随机移民扰动都依赖于时间t的条件下,给出了其半隐式Euler算法,并在Lipschitz系数是常数的情况下分别估计了近似误差.
A numerical method of stochastic population equations is discussed. Under the conditions that influ- ences of external environment and random migration perturbation of equations are depend on time t, a semi- implicit Euler algorithm is built, and approximate errors are estimated with Lipschitz coefficient being a constant, respectively.
