| Abstract: | In this paper, a class of two-step continuity Runge-Kutta(TSCRK) methods for solving delay differential equations where delay lies in the span of the current step is presented. Under certain conditions, we prove the convergence property of the method. Some examples show the efficiency of the method. |

| Keywords: | convergence singular delay differential equations two-step continuity Runge-Kutta method |
