Dynamic Decision Model in Evolutionary Games Based on Reinforcement Learning

In evolutionary games, it becomes more difficult to choose optimal strategies for players because of incomplete information and bounded rationality. For bounded rational players, how to maximize the expected sum of payoffs by learning and changing strategies is an important question in evolutionary game theory. Reinforcement learning does not need a model of its environment and can be used online, it is well-suited for problems with incomplete and uncertain information. Evolutionary game theory is the subject about the decision problems of multiagent with incomplete information. In this article, reinforcement learning is introduced in evolutionary games, multiagent reinforcement learning model is constructed, and the learning algorithm is presented based on Q-learning. The results of simulation experiments show that the multiagent reinforcement learning model can be applied successfully in evolutionary games for finding the optimal strategies.
