## Feigenbaum bifurcation approach to chaos

Click on the start button to see 100 iterations of the quadratic
map,

*x[i+1] = r · x[i] · (1.0 -
x[i])*
for each value of the grows constant, *r*. The iterations are
started with *x[0] = 0.5*. After that, the first 300
iterations are discarded and the next 100 are plotted.

You can zoom in on the bifurcation diagram by specifying the
limits of the r- and x-intervals. You can either type these into the
text fields or you can drag the mouse inside the plot area to
accomplish this.
