Bayesian Optimization Enhanced Deep Reinforcement Learning for Trajectory Planning and Network Formation in Multi-UAV Networks [PDF]
IEEE Transactions on Vehicular Technology, 2022 In this paper, we employ multiple UAVs coordinated by a base station (BS) to help the ground users (GUs) to offload their sensing data. Different UAVs can adapt their trajectories and network formation to expedite data transmissions via multi-hop ...

, 2023 This chapter discusses the trajectory planning of robot. First, the basic principle of trajectory planning is described, which is mainly determined by the geometric path and the motion law, and it is a motion law that defines time according to a given geometric path. Second, the characteristics of the joint space and the operational space are expounded.
