【 摘 要 】

This paper applies the variational iteration method for solving systems of nonlinear ordinary differential equations. The model under consideration in this work is the population dynamics model of two species. Our results show that the variational iteration method provides formulas to approximate the exact solution at every time value with a very cheap computation.
