345/3/8

[apg]

This rule is awkward to apgsearch, because it seems to get stuck occasionally (suggesting some sort of rare explosive object, or possibly a bug in the search program).

Anyway, there's an amusing natural p72 orthogonal ship: https://catagolue.appspot.com/object/xq ... 4/g8b3s345

Here's the soup that generated it:

Code: Select all

x = 16, y = 16, rule = 345/3/8

The rule also has a moderately common p24 diagonal ship:

This rule is awkward to apgsearch, because it seems to get stuck occasionally (suggesting some sort of rare explosive object, or possibly a bug in the search program).

After further experimentation, it doesn't actually get stuck permanently. It just spends 20 seconds (!) identifying the infinite-growth pattern in https://catagolue.appspot.com/hashsoup/ ... 4/g8b3s345 before continuing at a speed of ~ 700 soups per second.

Great to hear an update on apg 4.0! Is there going to be a limit to state amount so that people don't search huge-apgcode-having rules?

Great to hear an update on apg 4.0! Is there going to be a limit to state amount so that people don't search huge-apgcode-having rules?

Any apgcode with more than 1280 bytes is considered 'oversized'.

Also, the number of underscores in the apgcode is logarithmic in the number of states, and in particular 256-state Generations would only require 10 underscores. I don't think there's actually any limit in the number of states you can have in apgsearch, besides memory consumption -- the 2^64-state limit only applies to reading .mc files if I remember correctly.

MEGA HYPE FOR APG4.0.

Have you tried souping any larger than life rules yet? Bugs, or the variant with the 12RRO, seem like decent starting points

I'm noticing that there are many pseudo-still-lives listed in the census for this rule (xs8_rr being a major offender). Is this intentional, or is it by design?

My reluctance to commit to the arduous task of updating the object-separation code in classifier.h to work for multi-state rules. (At the moment it does 2-state range-1 rules correctly, ultimately resorting to an exhaustive search of partitions into islands, in order to avoid the confusion suffered by v3.x.)

I've noticed that the images are not animated. Are they going to be animated any time soon? What about for LTL?

calcyman,

You could also ask Calcyman to provide an RLE link on every object page.

That is what I am doing by highlighting this omission on the 'Oddities' thread.

viewtopic.php?f=7&t=2224&start=75#p48378

Are you interested in doing this?
