Скачать или смотреть Predator avoidance with k=40

Sub-optimal (excessive social behavior) predator avoidance for a swarm of N = 2,048 SPPs moving about a periodic bidimensional box and topologically interacting with a fixed outdegree k = 40.
The red circle represents the danger-detection area, i.e. the region of space where agents are able to detect the predator (located at the middle of the circle and moving 1.4 times faster than the agents.)

When the amount of social interaction is too high, the swarm’s response to the threat is too global and not effective enough in the area surrounding the predator. Note that the swarm is indeed responding at large scales, as evidenced by the global shift in the collective heading. However, due to the long range of the interaction, the information received by the agents surrounding the predator is not local enough for them to perform an efficient predator avoidance.
