How does the PTrie format work for compressing the Trie?

1

Wondering how you arrived at this compression format? Is it based on a research paper or anything, or how much does it compress the basic JSON structure of the `Trie`...

Example of how to move across or traverse a 2D tessellation like HyperRogue?

I just asked [How to "move" or "traverse" the hyperbolic tessellation in MagicTile?](https://stackoverflow.com/questions/75173044/how-to-move-or-traverse-the-hyperbolic-tessellation-in-magictile) on StackOverflow, but not sure anyone is going to be able to handle that since it's so...

I run this from [Chapter 74 of the Tao Te Ching on Wikisource](https://en.wikisource.org/wiki/Translation:Tao_Te_Ching#Chapter_74_(%E7%AC%AC%E4%B8%83%E5%8D%81%E5%9B%9B%E7%AB%A0)) (just picking a random page with what seems like incorrectly parsed text): ``` nodejieba.cut('民不畏死') [ '民不畏死' ]...

This will fix https://github.com/meltingice/psd.js/issues/287 I think, or something like this.

If my question on drawing a hyperbolic tessellation https://github.com/geoopt/geoopt/issues/205 is too involved, a simpler thing to do, which ChatGPT still is unable to figure out, is how to draw a...

Last question for now! How far is it capability-wise from generating a hyperbolic tessellation like [these](https://github.com/lancejpollard/ht.js)? What remains to be done to accomplish this using the general [K-Stereographic Model](https://andbloch.github.io/K-Stereographic-Model)? Could...

Looking at [geoopt/manifolds/stereographic/math.py](https://github.com/geoopt/geoopt/blob/27a1e6fd825e2de923b8493bb8baf514f3f089ea/geoopt/manifolds/stereographic/math.py) and trying to learn about hyperbolic geometry as I go, wondering if you could add some commentary to the functions. If anyone is in the mood to...

I asked [How does the hyperboloid model relate to A Universal Model for Hyperbolic, Euclidean and Spherical Geometries?](https://math.stackexchange.com/questions/4624636/how-does-the-hyperboloid-model-relate-to-a-universal-model-for-hyperbolic-eucl) on the Math StackExchange, wondering if you could shed light on that.

What needs to be done for TODOs in manifolds/stereographic?

I noticed in [manifolds/stereographic/math.py](https://github.com/geoopt/geoopt/blob/master/geoopt/manifolds/stereographic/math.py) there are a few TODOs: ```py # TODO: check numerical stability with Gregor's paper!!! @torch.jit.script def _mobius_coadd(x: torch.Tensor, y: torch.Tensor, k: torch.Tensor, dim: int = -1):...
