In this paper,continuous Runge-Kutta methods are applied to solve general nonlinear delay integro-differential equations,and a class of numerical algorithms is suggested.The stability of the numerical algorithms is studied,and it is proved that the numerical algorithms are asymptotically stable when the Runge-Kutta methods are (k,l)-algebraically stable and 0 < k < 1.Numerical experiments are used to validate the theoretical results and the effectiveness of the numerical algorithms.
