The purpose of this gist is to become aware of algorithms or existing solutions that I'm currently unaware of (I want to know what I don't know).

Below are some constraints and a few example problems leveraging said constraints. I believe the constraints and example problems are heavily related to bin-packing, but if anyone has additional info to steer me toward better algorithms or solutions that would be ideal.

Constraints:

container with set width and height
n number of items
n number of display styles
account for padding between items (but not container edges)
