Abstract: In the method for optimizing decision-making regulation and control, a first traveling sequence is obtained, where the first traveling sequence includes a first trajectory sequence of the vehicle in information about a first environment and first target driving behavior output by a behavior decision-making layer of a decision-making and control system based on the information about the first environment. A second traveling sequence is obtained, where the second traveling sequence includes a second trajectory sequence output by a motion planning layer of the decision-making and control system based on preset second target driving behavior and the second target driving behavior. The behavior decision-making layer is optimized based on a difference between the first traveling sequence and a preset traveling sequence, and the motion planning layer is optimized based on a difference between the second traveling sequence and the preset traveling sequence.

Abstract: In a driving policy determining method, for each object, a first target motion trajectory of the object is calculated on a premise that the object does not collide with another object that moves based on an initial motion trajectory. Then, for the ego vehicle, a second target motion trajectory of the ego vehicle is calculated on a premise that the ego vehicle does not collide with another object that moves based on a first target motion trajectory. Then, a driving policy is determined based on the second target motion trajectory of the ego vehicle and a first target motion trajectory of at least one game object. The foregoing operations are repeated until the determined driving policy matches an initial driving policy.

Abstract: An antenna subarray, an antenna array, and a polarization reconfiguration method and apparatus are provided. The antenna subarray includes m antenna elements. m is an integer greater than or equal to 2. The m antenna elements are placed at an interval of 360/m degrees in sequence.
