The logistic map is a simple quadratic function with the special property of describing the change in a system from a fixed point attractor [corresponding to a rigid, stuck, unhealthy dynamical process], to a periodic attractor, to chaos as a bifurcation variable increases in value. It originated in studies of population dynamics. [Excessively frequent remedy repetition may cause incurability by pushing the system dynamics to bifurcate excessively and end in chaos].
