The core research content of this topic is how to use limited energy resources to optimize multi-agent system performance. Considering the similarity between the agent clusters and the biological colonies, exploring the energy efficient utilization mechanism of biological colonies has important research value in improving the energy utilization performance of intelligent agent clusters. Firstly, this paper introduces the energy utilization mechanism of multiple biological colonies, and classifies them according to the differences in energy saving methods, fluid advantage utilization mechanism, fluid obstacle overcoming mechanism and heat exchange and diffusion mechanism. Then these mechanisms are summarized and analyzed, and a general model of efficient energy utilization is proposed. Finally, the challenges and development trends of energy efficient utilization mechanisms in multi-agent applications are discussed.1)
