Optimal control of an HIV within host model based on the article ?Resistance, Remission, and Qualitative Differences in HIV Chemotherapy? by Denise E. Kirschner and G.F. Webb using Pontryagin maximum principle with programs written in Mathcad. Numerical analysis and computational methods should be shown. Local and Global stability of the models should be worked out. The paper may be arranged as abstract; introduction/literature review; model with three variables(without treatment); stability analysis; optimal control problem (second model); numerical results/discussion; conclusion. 12 pages.
