An approximate solution of a model for HIV infection of CD4+ T cells

Abstract

In this paper, the approximate solution of the differential system modeling HIV infection of CD4+ T cells isobtained by a reliable algorithm based on an adaptation of the standard variational iteration method (VIM), which is called the multi-stage variational iteration method(MSVIM). A comparison between MSVIM and the fourthorder Runge-Kutta method (RK4-method) reveal that the proposed technique is a promising tool to solve the considered problem.
