Multi-ship Coordinated Collision Avoidance Decision Based on Improved Twin Delayed Deep Deterministic Policy Gradient [PDF]
Jisuanji kexue, 2023 At present,most models of collision avoidance algorithms take ships as single agent to make collision avoidance decisions,without considering the coordinated avoidance between ships.In the scenario of multi-ship meeting,it will lead to poor avoidance ...
