In this video we compare the responses of the Couzin leader model, the Cavagna spin model and their will-based enhanced versions, the will standard model and will spin model in two scenarios: a) response of 1000 agents to a single leader in the middle of a flock deviating from the flock's direction by 90 degrees; b) response of 2500 agents to a single-leader-deviation of 120 degrees. To visualize the response, we coded the color of agents according to their individual direction of motion. As can be seen, the responses of the willed models are much more intense in all cases.
