Real numbers do not exist for a computer [Les nombres réels n'existent par pour un ordinateur]
.2 X = (R+1)X - RX n n-1 n-1In the upper animation, the five following different valid formulations of the Verhulst dynamics are used:
X = X + (R(X - (X X ))) n n-1 n-1 n-1 n-1with the same initial value:
X = (RX ) + ((1 - (RX ))X ) n n-1 n-1 n-1
X = (((R+1) - (RX ))X ) n n-1 n-1
X = ((R+1)X ) - ((RX )X ) n n-1 n-1 n-1
X = ((R+1)X ) - (R(X X )) n n-1 n-1 n-1
X = 0.5 0[More information -in english/en anglais-]
