No I just meant WFC as an algorithm for solving problems. https://github.com/mxgmn/WaveFunctionCollapse It's one of the coolest things I've ever seen. I guess I've been pronouncing it wrong though. It's wave function collapse, not…

This is not Wave Function Collapse. This is a constraint solver. The goal of the original algorithm ( https://github.com/mxgmn/WaveFunctionCollapse ) is to infer the constraints from a sample, and then run a constraint solver. Hard-coding…
