      I would also add one more to NA to make it as wide as it should be. It’s pretty skinny here.

    Intelligence is knowing I could optimize this with annealing and a decent error function.

    Wisdom is deciding not to get nerd-sniped like that.

      I feel a tingling in my hands. An algorithm to optimize for n arbitrary polygons

      Apparently I am a fool.

      What you’d do is, you pick a representative set of points from a world map, e.g. by reducing it to a low resolution, or by sampling with blue noise. Each point gets a 32-bit integer. For up to 32 circles, you check if each point is inside or outside the circle, and mark one bit accordingly. Every region created by these overlapping circles now has a unique ID for all points inside that region.

      Scoring groups points by ID, finds whether each group contains more land or water points, and counts all the points outside that majority. That sum is your error.

    my own attempt at it

    as can be seen with this diagram, i prefer straight lines over circles when it comes to geopolitics

    also, i’m sorry if this offends somebody somehow

    The entire southeast Asia, which makes up maybe half the majority of the world population disappeared.

        India isn’t really missing so much as not distinguished, but also that.

        Every island is missing, starting by size with Greenland.

        Northern Canada is pointed instead of concave with Hudson’s Bay. Antarctica is also missing but that counts more as a stylistic choice because it’s so frequently done.

      It was the first thing I noticed missing too, but it’s “only” 0.7 billion people.

      It probably should be integrated into Australia somehow, to keep circle count low.

        I would say it’s east Asia and South Asia that are missing, not “south east”. It’s like 3 billion isn’t it?

          Uhh, so you’re reading that all as Persia, Russia and Mongolia, then?

          Yeah, India and China are each over a billion, and then with SE Asia it could easily be 3.5. We’re at eight, so that’s not quite half, but it’s close.

          not “south east”.

          Y’know, Indonesia, Thailand, Vietnam, Cambodia, Laos and friends. Have you never heard it grouped that way?

    I love this. I’m guessing there’s a better way to choose circles, though.

    Why have one for the Great Australian Bight? Just so it doesn’t end up being an entire circle? That’s kind of a missed opportunity to do a Philippine Sea circle and include SEA.

    Edit: What about one for each continent, a couple for the Indian ocean, and then a big Pacific Ocean one that takes out of Australia, East Asia (forming SEA) and the two in America?
