英文摘要：

The formulation and the solution character of time-varying population system with age-dependence and spatial diffusion have been studied, but the optimal boundary control is hard to solve, it is necessary to give a new algorithm for the optimal boundary control. The iterative algorithm is constructed for the optimal boundary control of time-varying population system with age-dependence and spatial diffusion by using the auxiliary principle technique. The convergence of iterative sequences generated by the algorithm is also proved.
