Usage

gc_utility_rcpp(
  a_group_centroid,
  b_group_centroid,
  radius,
  cell_distances,
  stop_utility,
  number_agents
)

a_group_centroid: Numeric denoting the power to which to take the utility.
b_group_centroid: Numeric denoting the slope of the utility function.
radius: Numeric denoting the radius of the agent.
cell_distances: Numeric vector denoting the distance of each cell in the centers to the predicted group centroid.
stop_utility: Numeric denoting the utility of stopping. Is used to ensure the agents do not freeze when they are too far away from each other.
number_agents: Numeric denoting the number of ingroup members.

Numeric vector containing the group-centroid-related utility for each cell.
