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

obooobooboboooob$
bbbobobbobbbbbob$

bbooooobooobobob!
The rule also has a moderately common p24 diagonal ship:

After further experimentation, it doesn't actually get stuck permanently. It just spends 20 seconds (!) identifying the infinitegrowth 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 hugeapgcodehaving rules?
This post was brought to you by the letter D, for dishes that Andrew J. Wade won't do. (Also Daniel, which happens to be me.)

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 256state 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 2^64state 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 pseudostilllives listed in the census for this rule (xs8_rr being a major offender). Is this intentional, or is it by design?
x₁=ηx
V ⃰_η=c²√(Λη)
K=(Λu²)/2
Pₐ=1−1/(∫^∞_t₀(p(t)ˡ⁽ᵗ⁾)dt)
$$x_1=\eta x$$
$$V^*_\eta=c^2\sqrt{\Lambda\eta}$$
$$K=\frac{\Lambda u^2}2$$
$$P_a=1\frac1{\int^\infty_{t_0}p(t)^{l(t)}dt}$$

My reluctance to commit to the arduous task of updating the objectseparation code in classifier.h to work for multistate rules. (At the moment it does 2state range1 rules correctly, ultimately resorting to an exhaustive search of partitions into islands, in order to avoid the confusion suffered by v3.x.)
