Consider the following picture of a phase plane which help us distinguish between regular and chaotic motion. The entire phase plane is divided into two types of regions: (i) the regular domain corresponding to the different well-defined islands of closed curves and (ii) the chaotic domain corresponding to the randomly scattered black dots. So the question is the following: is there a computational way to measure the area of these two domains? Let's say 55% of the phase plane is chaotic and 45% is regular.
Many thanks in advance.
I want to calculate the portion inside the outermost star-like thick black curve occupied by the red circled white regions.
Some more examples
