Model parameter Description Fixed value Range of values
N Total group size (individuals) 40 2, 5, 10, 15, 20, 25, 30, 40, 50, 60, 80, 100
R C Radius of collision avoidance 2 -
R O Radius of orientation 15 -
ξ Standard deviation of added environmental noise/error 0.1 -
w Weighting towards individual navigation (tactic factor) - 0.01, 0.02, 0.04, 0.06, 0.08, 0.1, 0.12, 0.15, 0.2, 0.25, 0.3, 0.4, 0.5, 0.7, 1
k Number of influential nearest neighbours - 1, 2, 3, 4, 5, 7, 9, 12, 15
ϵ Standard deviation of individual navigation error - 0, 0.2, 0.5, 1, 1.5, 2, 3, 5
  1. Parameters have either no units or arbitrary distance units.
  2. Fixed parameters are the same throughout all simulations. Parameters that have a range of values are explored in simulations using each combination of values in turn.
