| Abstract: | The convergence of the weighted format method in solving non-linearity stochastic delay differential equations was studied.In the circumstance of measurement noise,the convergence of weighted format method in solving non-linearity stochastic delay differential equations was gained.By using the property of stochastic variable being subordinated to normal distribution,the equal local convergence,average local convergence and strong convergence order of weighted format were 2,1 and 1. |
