The continuous logistic model is described by the differential equation , where is known as the Malthusian parameter. This Demonstration allows you to integrate this DE numerically with several Runge–Kutta methods with orders from 1 up to 3, with constant step size and initial value . This procedure illustrates chaos and bifurcation. In particular, by using the Euler method, the map is very similar to the classic logistic map, but other RK methods give different and more interesting maps.
