Click da green flag and watch dat duck get closer and closer do its nest. The process goes slow, so Turbo Mode (SHIFT+GREEN FLAG) is recommended to speed it up. Fun fact: This was originally going to be a dot going to a goal dot, but when I added the line on the moving dot to show its direction, it looked like a duck bill. I then made it all duck themed.
This is a simple genetic algorithm. Here's an in-depth explanation (although simplified a bit) So GAs are where you make a means of doing something (in this case, getting to the nest) and make a way of scoring how well it did. (in this case, the distance from then nest, where lower is better) then you make some random things trying to do that. Since it starts out random, it won't be very good. But you take the one that did the best and make new versions, slightly different, and test those. Then take the one that did best out of those new editions and repeat the process.
