Could you try explaining it in a comment? Not the general principle, but just the rules for one particular automaton. Whichever one is your favourite. Or Amazing Dragons, if you don't have a favourite.

The amazing part of cellular automata is the emergence of complicated behaviour from simple rules. Life's rules can be written in three sentences, maybe less.

Forgive my quibbling, but I don't understand what this is doing that other projects in this space haven't done before. Adding states and transition rules to edges is new to me...

I did try running your project, but I had to tweak it to get it to work with the instructions in the repo. I seem to be missing a few packages -- mpmath, sympy, typing_extensions. Can you add those to the requirements.txt file?

Let's see if I understood this right. For the Betweenness Amazing Dragons rule:

* Compute the "betweenness" of each living cell, which is 1 divided by its degree. Cells which are not connected to anything have infinite/undefined betweenness, but it doesn't matter.

* Then, for each cell, sum up the betweenness of its connected neighbours.

* If the total betweenness of a dead cell is in the range [(1.3, 3.6)], it is born and becomes alive at the next generation.

* If the total betweenness of a living cell is in the range [(0.9, 2.6)], it survives and remains alive to the next generation.

* Exception: any cell with 0, 1, 7 or 8 neighbours (in total, ignoring betweenness) dies anyway after the rules above were applied.

... That's not quite right, there's some references to "eligibility" that I can't make sense of. What else am I missing?
