Web14 de abr. de 2024 · However, these 2 settings limit the R-tree building results as Sect. 1 and Fig. 1 show. To overcome these 2 limitations and search a better R-tree structure from the larger space, we utilize Actor-Critic [], a DRL algorithm and propose ACR-tree (Actor-Critic R-tree), of which the framework is shown in Fig. 2.We use tree-MDP (M1, Sect. … Web18 de mar. de 2024 · Afterward, a neural network-based actor-critic structure is built for approximating the iterative control policies and value functions. Finally, a large-scale formation control problem is provided to demonstrate the performance of our developed hierarchical leader-following formation control structure and MsGPI algorithm.
