Figure 5From: Copycat dynamics in leaderless animal group navigation Navigational efficiency, E , against overall group size, N , for different values of w . The number of influential neighbours is (a) k = 1, (b) k = 7, (c) k =15, (d) k = N. In (d), each individual responds to the direction of movement of every other individual in the group (regardless of group size). Results shown are the average of 100 simulation runs.Back to article page
