SG> Just went down a 2-hour rabbit hole on the "wave function collapse"
algorithm that emerged in graphics in 2016 but just
SG> came onto my radar... Has anyone else explored it already?

I think I 'get' from our myriad discussions about both dual-fields and
bidirectional search why you got "rabbit holed" by this...
FWIW my "associative memory" self "squinting" from 100k ft saw some
near-adjacents:
https://en.wikipedia.org/wiki/Hashlife
On one hand it is "memoization" up front, but it also has a
possibility for a WFC style application for a *dynamic* landscape?
https://en.wikipedia.org/wiki/Vector_quantization
SOFMs seem like an apt near-adjacent to what you are maundering on?
https://en.wikipedia.org/wiki/Attention_(machine_learning)
The Text-Image transformers of DALL-E (et alia) seem to be a softer
version of the constraint business?
I may be overgeneralizing or missed the focus of your fascination?

Many of you have written versions of constraint propagation algorithms
in one form or another. I like how this is framed by satisfying local
constraints with tiles (forward) and global constraints with overlaps
(backward propagation). Of course, the name of the algorithm may be
metaphorical to QM as is its use of superposition for local stacks of
possible states, but I can't help wonder how Wheeler-Feynman Absorber
Theory or Cramer's Transactional Interpretation might be cast as
similar kinds of the same algorithm.
more general applications:

always like Dan Shiffman's Coding Train
