2D maximum Lyapunov exponent (MLE) bifurcation diagrams in the plane: (a) (, α); (b) (d, α); (c) (d, c); and (d) (α, c) depicting the region of complex dynamics of system (2a)–(2e) with respect to the MLE (right column bar); the system parameters are: a = 0.05; b = 0.03; c = 6; d = 3; e = 2;  = 1; k = 2. Initial conditions are (x₀; y₀; z₀; ) = (1; 1; 1; 0.1; 1) (color figure online).
