Abstract
AbstractIn this chapter, the optimal control strategy for organism is investigated by using adaptive dynamic programming (ADP) method under the architecture of nonzero-sum games (NZSGs). Firstly, a tumor model is established to formulate the interaction relationships among normal cells, tumor cells, endothelial cells and the concentrations of drugs. Then, the ADP-based method of single-critic network architecture is proposed to approximate the coupled Hamilton-Jacobi equations (HJEs) under the medicine dosage regulation mechanism (MDRM). According to game theory, the approximate MDRM-based optimal strategy can be derived, which is of great practical significance. Owing to the proposed mechanism, the dosages of the chemotherapy and anti-angiogenic drugs can be regulated timely and necessarily. Furthermore, the stability of the closed-loop system with the obtained strategy is analyzed via Lyapunov theory. Finally, a simulation experiment is conducted to verify the effectiveness of the proposed method.
