This function helps us to plot the improvement in Alice's expected payoff as a function of a
and b
, if Alice chooses to fire at the air in her second shot, in a two round game. Psi
is the initial state of the quantum game, n
is the number of rounds, a
is the probability of Alice missing the target, b
is the probability of Bob missing the target, and
alpha1, alpha2, beta1, beta2
are arbitrary phase factors that lie in -pi to pi that control the outcome of a poorly performing player.
