I read this months ago, and the impression I was left with is that this technique is simply a fancily-named variant of any normal tree-based search algorithm. You have constraints which can be represented on your search, and then you attempt to navigate the hyperspace finding a configuration which matches. I really can't see how this isn't "wavefunction collapse" and is rather just, "search." But I feel like I must be missing something. If this isn't right, can someone explain to me why it's not right?
