Asad A, Freihat, M. Zurigat and Ali H. Handam, The multi-step homotopy analysis method For Modified Epidemiological Model for Computer Viruses, Afrika Mathematika, 26 (3) (2015), 585-596.

In this paper, we consider the modified epidemiological model for computer viruses (SAIR) proposed by Piqueira and Araujo (Appl MathComput 2(213):355?360, 2009). The multi-step homotopy analysis method (MHAM) is employed to compute an approximation to the solution of the model of fractional order. The fractional derivatives are described in the Caputo sense. Figurative comparisons between theMHAM and the classical fourth-order Runge-Kutta method reveal that this method is very effective. The solutions obtained are also presented graphically.
