  • Publication number: 20230297859
    Abstract: The present disclosure relates to a method and apparatus for generating a multi-drone network operation plan based on reinforcement learning. The method of generating a multi-drone network operation plan based on reinforcement learning includes defining a reinforcement learning hyperparameter and training an actor neural network for each drone agent by using a multi-agent deep deterministic policy gradient (MADDPG) algorithm based on the defined hyperparameter, generating Markov game formalization information based on multi-drone network task information and generating state-action history information by using the trained actor neural network based on the formalization information, and generating a multi-drone network operation plan based on the state-action history information.
