k = 15. ϵ gives the standard deviation of the individual navigational error. Results shown are the average of 100 simulation runs. The black triangles at w = 1 indicate the theoretical expected navigational efficiency for an individual random walker navigating asocially with the given value of ϵ. Plots for other values of k are qualitatively very similar and are not shown here.
