Chaotic Model for Development of HIV Virus

In this paper we focus on the numerical treatment of nonlinear system of differential equations arises from biological model. Three numerical methods namely, Runge Kutta method differential transform and multistep differential transform methods are applied to solve the system. Some numerical examples are solved to show the validity and applicability of these numerical methods. Numerical results show clearly that the multistep differential transform method is one of the most efficient and accurate method in comparison with its counterparts.
