, the problem of trajectory planning is transformed to parameter optimizing, and then auxiliary population-based quantum differential evolution algorithm (AP-QDEA) is applied as a tool to optimize the objective function, and the design parameters of the whole homing trajectory are obtained. The proposed AP-QDEA combines the strengths of differential evolution algorithm (DEA) and quantum evolution......

agents consisting of multiple leader agents and multiple follower ones, a flocking behavior method with multiple leaders and a global trajectory was proposed. In this flocking method, the group leaders can attain the information of the global trajectory, while each follower can communicate with its neighbors and corresponding leader but does not have global knowledge. Being to a distributed control......
