New counterterror measures: Feedback Nash equilibrium of a multiplayer differential game

In this study, we consider the new trend of counterterror measures and the economic growth differential game. The feedback Nash equilibrium of this game is acquired by dynamical programming. We also characterize the feedback strategies for the government and terrorist organization. The optimal strategy in our study is then compared with a two-player zero-sum feedback equilibrium reported previously. Finally, we discuss the effectiveness of the counterterror game.
