摘　　要：In this study, we improve L6vy walk model, and make it suitable for simulating the collective behaviours of humans. Here we show how rescuers find missing persons by collective cooperative search in a natural background. In the search process, the search strategy represents an optimal algorithm which is used to maximize the success rates for finding missingpcrsons. We simulate the rescuer＇s movement pattern, and find some basic laws governing the rescuer＇s cooperative search. For example, the probability that each rescuer finds missing persons shows a power law distribution.In this study, we improve L6vy walk model, and make it suitable for simulating the collective behaviours of humans.
