Algorithm 1. Calculating return value of function fev

1: function fev (Qmodek, $QValue\left(t\right)$, ${\xi }_{jk}$).

2:  acc ← 0

3:  for z←1 to R do

4:   if Q’z(t) = QRzk then

5:    acc ← acc + 1

6:   end if

7:  end for

8:  suit ← acc/n

9:  affectedSuit ← suit * (1 − ${\xi }_{jk}$).

10:  return affectedSuit.

11: end function
