  • \$\begingroup\$ Excellent image. I've been working on something similar using ellipses myself. (Not posted yet.) However my GA hardly ever manages to use a single ellipse to represent a star, electing instead to have a bright one in the background with multiple dark ones overlapping it. I wonder why yours discovers this and mine doesn't. \$\endgroup\$ Commented Feb 3, 2016 at 3:54

    \$\begingroup\$ @Nathaniel I noticed on some runs that it does this as well. I use a very slight penalty (score increase) based on the program size, which is intended to favor solutions using fewer ellipses. I don't really know if it's working, but since I implemented it I haven't seen the "multi-ellipse star" as much. \$\endgroup\$ Commented Feb 3, 2016 at 4:05
