Re: Use Smoothiness to classify rules

Update: The aforementioned diagonal is indeed a signature of periodic behavior. Diagonal is separated by 20 steps, which is the time required for an speed c/1 spaceship to traverse the torus space. If the native spaceship has a speed of c/2, then the period would be torus_width * 2. This signature i...

Re: Use Smoothiness to classify rules

I had a closer inspection at the totalistic rulespace and scanned 20% of the 2^18 rules. It is obvious that TCA-rulespace constitutes a higher proportion of quiescent (quick stabilising) rules, whereas a random rule from NTCA rulespace is less likely to be quiescent. TCA quiescence rate ~25% NTCA qu...

Re: apgsearch - haul requests

(*:The annotation here includes flagging for diagonal strips only.) Wouldn't it be possible to automatically detect diagonals to reduce the number of rules that have to be manually reviewed? That will be the idea. But we needs some kind of scalar metric (0/1). EDIT: To disambiguate, I meant strip a...

Sorry for being poorly annotated. The axes haven't changed much from last plots. It's still time-points/step-numbers. At stepnumber=1, the soup is initialised with 50% density (which I consider max-entropy distribution). A trajectory of 36 steps was generated, and correlation/pairwise metric is calc...

Re: Use Smoothiness to classify rules

Existence of diagonal lines are strongly indicative of complex dynamics (sufficient but not necessary, though with very rare outliers). It'd be great if some can suggest how to abstract this information. An examplar collection can be found here Example: b1ce2e3eijkr4ejqrtwz5cn6aikn7es01c2in3aejkr4ej...

Re: Use Smoothiness to classify rules

Instead of expressing dynamic difference purely on the difference between rulestrings, weight the changed neighborhoods based on the frequency in which they appear naturally in the two rules. (I say check both rules to preserve transitiveness of the dynamic difference and give a more refined estima...

Re: Use Smoothiness to classify rules

I still think it would be a better determinant of what constitutes a "superficially related rule", considering that even though specific profiles (what I think you call trajectories) can vary between rules, certain transitions are basically always more or less important than others (e.g. 2a or 2e a...

Re: Use Smoothiness to classify rules

There's no real way to do this purely theoretically, because - as I'm sure you realized - the Hamming distance treats all bits equally when we know they should not be. (e.g. B0 definitely changes dynamics much more than S8) However, in my mild experimentation with non-totalistic rules there is one ...
