Generally, it is difficult to obtain analytical solutions of DDEs, so many scholars pay their attention to numerical analysis for DDEs.

Linear multi-step method, θ-method, and Runge-Kutta method are effectively numerical methods for solving DDEs and NDDEs.

我们知道，求解各类延迟微分方程，线性多步法，θ-方法和Runge-Kutta方法都是非常有效和常用的方法。
