Navigational efficiency, E , against number of influential neighbours, k . The weighting towards individual navigation is (a) w = 0.01, (b) w = 0.02, (c) w = 0.06, (d) w = 0.1, (e) w = 0.15, (f) w = 0.25, (g) w = 0.5, (h) w = 1.0. ϵ gives the standard deviation of the individual navigational error. Results shown are the average of 100 simulation runs. The black triangles in (h) indicate the theoretical expected navigational efficiency for an individual random walker navigating asocially with the given value of ϵ.
