Packing Geometric Shapes (erich-friedman.github.io)

Early in my generative art, I spent a lot of time packing various small shapes together, it was a fun process to figure out how to maximize the coverage without leaving large gaps. For example, a piece with almost every shape I was using: https://digcon.art/details.html?key=river-in-the-woods

I've been pondering what an algorithm would look like that does this. Given a bunch of boxes of various sizes and weights, and a room of a given dimension, what's the most efficient arrangement to make sure they all fit?
