title: Simulating cooperative behavior in human collective search pattern.
abstract: In the world, great natural disasters frequently occur. Along with these disasters, large-scale cooperative searches for missing persons are exigent. Because of the lack of experiments to reproduce the disaster rescue processes, our understanding of how to regulate the collective cooperative searches is still elusive. Here we use an improved Lévy walk model to simulate the rescuers' movements in which direction choice is considered. In our study, we systematically analyze the diffusive mechanism of rescuers' movements, and find that the search pattern shows a high degree of spatial order which displays some inherent features. Our results also indicate that cooperative search promotes rescuers' movements to disperse determinately.
