File:Julia set (Rev formula 01).jpg

Summary[edit]

Julia set, a fractal. Here created using the reversed formula in an iterated function system.

Formula used:

${\displaystyle z_{n+1}={\sqrt {z_{n}-c}}}$

One of the two roots is selected at random and then after a number of pre-iterations (10-20) the position of ${\displaystyle Z}$ is constantly plotted after each iteration. The method is very much like the "random game" IFS method.
