Description

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 are selected from some kind of function system and then after a number of pre-iterations (10-20) the position of ${\displaystyle Z}$ is constantly plotted after each iteration. The method is wery much like the "random game" IFS method.

Parameter c is near c = -0.750357820200574 +0.047756163825227 i
