Abstract

Near-optimization is important as optimization for theory of stochastic control and applications. In this work, we consider a stochastic viral model incorporating the lytic and nonlytic immune responses where the system is governed by stochastic differential equa- tions (SDE's). According to the adjoint equations, we estimate the error bound for the near optimality. Then, using the Hamiltonian function, Ekeland's variational principle and some basic estimates for state processes and adjoint processes , we will prove sufficient and necessary conditions to minimize the cost functional. Using control treatment, numerical illustrations are introduced to compare with theoretical.
