fermi_imitation_function

ludics.main.fermi_imitation_function(delta, choice_intensity=0.5, **kwargs)

returns the value of the Fermi logit function \(\frac{1}{1 + e^{\beta\Delta(f)}}\)

Parameters:

• delta: float - the difference between a player's current fitness and the fitness they consider
• choice_intensity: float - the choice intensity of the equation

Returns:

• float - the value of the Fermi logit function
