Low-poly image generation using evolutionary algorithms in Ruby (2023)

Great write-up, I like the fitness graphs a lot.<p>I did something similar in Julia a while ago in an attempt to learn the language: <a href="https:&#x2F;&#x2F;www.basjacobs.com&#x2F;post&#x2F;2020-11-18-image-triangulation-with-julia&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.basjacobs.com&#x2F;post&#x2F;2020-11-18-image-triangulatio...</a>

Camme for the evolutionary stuff (wrote mh PhD on it).<p>Left having leaned that you can switch Tail Call Optimisation on or off in Ruby code.

I made some image generation with CLIP and Evolutionary algorithms not so long ago[1] and the results had a bit more life than I was expecting. It is still a contested area of research and you have some cool stuff like CLIPDraw[2] where they use gradient decent to approximate a vector to the embeddings of CLIP.<p>[1] <a href="https:&#x2F;&#x2F;snats.xyz&#x2F;pages&#x2F;articles&#x2F;optimizing_images.html" rel="nofollow">https:&#x2F;&#x2F;snats.xyz&#x2F;pages&#x2F;articles&#x2F;optimizing_images.html</a> [2] <a href="https:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;2106.14843" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;2106.14843</a>

Related, but in C language and with a different search algorithm: <a href="https:&#x2F;&#x2F;github.com&#x2F;antirez&#x2F;shapeme">https:&#x2F;&#x2F;github.com&#x2F;antirez&#x2F;shapeme</a>

Very cool! Like others here I&#x27;ve done something similar about a decade ago [0], but only with inheritance and mutation. This was C++ and Qt.<p>[0] <a href="https:&#x2F;&#x2F;github.com&#x2F;jeroenvlek&#x2F;evopic">https:&#x2F;&#x2F;github.com&#x2F;jeroenvlek&#x2F;evopic</a>

I tried something related many years ago; to evolve a image format that should be tiny:<p><a href="https:&#x2F;&#x2F;medium.com&#x2F;@JuliusHuijnk&#x2F;experiment-in-evolving-the-smallest-image-file-format-6c689e7ec79e" rel="nofollow">https:&#x2F;&#x2F;medium.com&#x2F;@JuliusHuijnk&#x2F;experiment-in-evolving-the-...</a><p>To be honest I haven&#x27;t yet read the original article, since it&#x27;s huge. It seems to aim for something compareable.

Where is the scrollbar?

I did something similar to this once and used a similarity algorithm for fitness. The result was really neat, the output image looked very similar to the input image when you were zoomed out but when you zoomed in it was unrecognizable. It was a really interesting result!

John Koza has something like three or four books on Genetic Programming. It&#x27;s all in Lisp and I enjoyed working with different examples from his books. If I ever have enough free time, I&#x27;d like to go back and work with it again for a while.

This was cool on 4chan 10 years ago. I remember writing my own implementation using lots of unsafe C#.

There seems to be a competition on making blogs as difficult to read as possible lately.<p>A monospaced font with narrow line spacing. 40 years of typesetting tech and 500 years of typography and insights on what makes a text readable thrown out of the window.<p>To get what exactly? Some fake retro charme?<p>I gave up reading after the first three paragraphs.
