As one of the major contributions of biology to competitive decision making,evolutionary game theory provides a useful tool for studying the evolution of cooperation.To achieve the optimal solution for unmanned aerial vehicles(UAVs) that are carrying out a sensing task,this paper presents a Markov decision evolutionary game(MDEG) based learning algorithm.Each individual in the algorithm follows a Markov decision strategy to maximize its payoff against the well known Tit-for-Tat strategy.Simulation results demonstrate that the MDEG theory based approach effectively improves the collective payoff of the team.The proposed algorithm can not only obtain the best action sequence but also a sub-optimal Markov policy that is independent of the game duration.Furthermore,the paper also studies the emergence of cooperation in the evolution of self-regarded UAVs.The results show that it is the adaptive ability of the MDEG based approach as well as the perfect balance between revenge and forgiveness of the Tit-for-Tat strategy that the emergence of cooperation should be attributed to.
