For the problem that the traditional flocking approaches with “averaged” velocity coordination strategy can not realize the fission behavior from a coherent flock into multiple sub-groups under external conflicting stimulus, the information entropy is deployed to formulate the information coupling degree(ICD) index with the information of neighbor’s velocity, distance, number and its own perception range. Then, an ICD-based “min-max” velocity coordination strategy is established.
Together with the “long range attraction/short range repulsion” position regulation method, self-organized fission behavior is achieved under external stimulus. Simulation results show that the flocking system under this motion law is able to achieve the fission behavior with equal size from a probabilistic perspective. In addition, this approach has better fusion performance than traditional flocking methods.
