That's very interesting

It seems the default mutation parameters are a bit low, if you increase it it may lead to better results

I think the main problem with this is that it's using a fixed number of polygons, and apparently is mutating their vertice positions.

If it could be changed for a range of polygons (with a range of vertices, let's say from 3-6) maybe it can converge faster (and better)

But it is nonetheless a very nice experiment. GA/GP is one of those things that really can work with "untractable" questions.
