Tridimensional high resolution visualization of the Verhulst dynamics -'Time Ships', a Tribute to Stephen Baxter- [Visualisation tridimensionnelle haute résolution de la dynamique de Verhulst -'Les Vaisseaux du Temps', un hommage à Stephen Baxter-].
X = 0.5 0
X = RX (1 - X ) n n-1 n-1Here, in this computation, the growing rate 'R' is no longer constant but changes its value periodically using the following arbitrary cycle:
R3 ==> R3 ==> R3 ==> R3 ==> R2 ==> R2 ==> R2 ==> R1 ==> R1 ==> R1 ==> R1 ==> R2 ==> R2 ==> R3 ==> R3 ==> R2 ==> R1 ==> R1 ==> R1 ==> R1 ==> R2 ==> R2 ==> R3 ==> R3 ==> R2 ==> R2 ==> R1 ==> R1 ==> R1 ==> R1 ==> R1 ==> R1where {R1,R2,R3} are respectively the three coordinates of the current point inside the following domain [3.173,3.376]x[3.700,3.850]x[2.500,4.000]. Only the points corresponding to a dynamical system with a negative Lyapunov exponent are displayed.
