Embodiment Construction

[0085] Reinforcement learning method is a research hotspot in recent years. The core algorithm of the famous AlphaGo uses reinforcement learning algorithm. Reinforcement learning algorithms are widely used to solve intelligent decision-making problems, or sequential decision-making problems. Applying reinforcement learning to trajectory planning, the intelligent aircraft can get a reward from the environment every time it walks a certain distance, and the current state is transferred to the next state according to certain rules. The intelligent aircraft flies a certain distance again and iterates repeatedly. Until reaching the destination, the goal of the entire algorithm is to maximize the cumulative reward obtained. The application of reinforcement learning to path planning has set off a heat wave, including using reinforcement learning to solve the classic traveling salesman problem.

[0086] The present invention will be further described below in conjunction with the acc...
