vectorized_replicator_equation()

Vectorized computation of the replicator dynamics for three-strategy two-player games.

Parameters:

  • x1 (numpy.ndarray) – Two-dimensional array containing the frequency of strategy 1 at each grid point.

  • x2 (numpy.ndarray) – Two-dimensional array containing the frequency of strategy 2 at each grid point.

  • x3 (numpy.ndarray) – Two-dimensional array containing the frequency of strategy 3 at each grid point.

  • game (egttools.games.AbstractReplicatorGame) – Two-player game object used to compute expected fitness values.

Returns:

Replicator gradients for the three strategies over the grid.

Return type:

tuple[numpy.ndarray, numpy.ndarray, numpy.ndarray]
