I could probably just reflect the spaceships since I have that technology (and it works with the same oscillator), but I won't do that rn.

Oh, duh. I could've just used the converting reaction.

EDIT: I apparently never discovered a c/3d-to-c/6o reaction, but I did find one where the reverse happens, so my bad.

I've got a strong feeling this 6c/24 can be turned into a puffer if you have two interacting copies.

Speedrunner Niftski just beat the any% world record for Super Mario Bros.: 4:54.332, a two-frame (33 millisecond) improvement over the previous one. The speedrun would have to be just four frames (67 milliseconds) faster to be perfect.

Rob's p16 is a period-16 oscillator that was found by Rob Liston on February 9, 2020 using Adam P. Goucher's apgsearch, and first noticed by a human the next day.

The phrasing here is hilarious.

I had a half-baked idea regarding measuring the frequency of evolutionary sequences.

The measuring process goes as follows:

Take all n-ominoes and n-plets with a certain number of cells

See how many eventually evolve into the sequence of interest

Divide the number of n-ominoes and n-plets that evolved into the sequence by the total number of possible n-ominoes and n-plets

Take this traffic light predecessor for example:

Code: Select all

x = 5, y = 3, rule = B3/S23
2bo$2ob2o$2bo!

Let's figure out its frequency among tetrominoes and tetraplets. There are tetraplets and 5 tetrominoes (27 total)

Code: Select all

x = 54, y = 46, rule = B3/S23
7b2o6b3o6b4o6b3o6b2o$7b2o7bo19bo7b2o14$4o6b3o7b3o7b2obo6b2o8b2o$13bo8b
o9bo9b2o8bo$53bo7$2o8b2o8b2o8b2o8b2o8b2o$2bo9bo8b2o8bo9bo8b2o$2bo8bo20b
o7bo7$obo7bo9bo9bo9bo9bo$bobo7b2o8b2o8bobo7bo9bo$13bo7bo10bo9bo8bo$43b
o6bo7$bo8bo9bobo7bo$obo7b2o9bo9b2o$bo8bo11bo7bo!

And we see that three of them evolve into that specific predecessor.

So 3 out of 27 (or 1/9) of all tetrominoes and tetraplets evolve into the sequence.

Thus, the sequence's frequency among tetrominoes and tetraplets is 1/9, or 11.1%. You could scale this up for pentominoes and pentaplets, hexominoes and hexaplets, etc. or do it with different sequences.

I'll post this in an appropriate thread outside of the sandbox when I get time.

Idk, thought it would be cool.

I've come up with a dumb generalization of INT rules that I call "globally non-totalistic". Each whole condition in the rulestring must have the same INT condition(s) attached to it. For example, B2e5e6e/S3e6e. All conditions are succeeded by the exclusion of any arrangements besides "e".

Now, since 0,1,7, and 8 have zero or very few arrangements, I'm thinking of excluding those from requiring a non-totalistic condition, but every other number needs one.

Some examples

B2-a3-a4-a/S2-a3-a8: Fairly stable rule with two common high-period oscillators and no common spaceships.

Code: Select all

x = 47, y = 3, rule = B2-a3-a4-a/S2-a3-a8
14b3o10b3o$bo13bo11bobo11b6o$o5b3o5b3o10b3o!

B2ek3ek4ek/S2ek3ek: Uninteresting rule that has period-2 checkerboard oscillators, which can be easily extended.

Code: Select all

x = 47, y = 16, rule = B2ek3ek4ek/S2ek3ek

o$6bobo7bobobobo8bobobobo$bo5bo9bobobobo8bobobobo$o5bobo7bobobobo8bob
obobo!

B3-ek/S2-ek3-ek4-ek: Pretty much the same as rule 2, but the checkerboards are still lifes with the occasional rotor.

Code: Select all

x = 0, y = 0, rule = B3-ek/S2-ek3-ek4-ek
#C [[ RANDOMIZE2 ]]
!

B3-n/S2-n3-n4-n: One of the more interesting rules of the bunch. An explosive rule that looks a lot like life, and has some small stable patterns. There are two common spaceships and a p20. The smallest exploding pattern is 7 cells.

Code: Select all

x = 33, y = 23, rule = B3-n/S2-n3-n4-n
12bo10bo6bo$3o8b2o9b3o4bobo$11b3o8bobo4bob2o$23bo8bo17$16bo$15b3o$15b
3o!

I might make a post going over this rule in more detail.

B3-n5-n/S2-n3-n5-n: Another interesting rule. a somewhat chaotic rule with a few common oscillators (including one p88) and one common spaceship.

Code: Select all

x = 35, y = 15, rule = B3-n5-n/S2-n3-n5-n

Code: Select all
x = 33, y = 23, rule = B3-n/S2-n3-n4-n

Far more interesting, in my opinion, is this rule -S4a, preserving most of the rule's dynamics while not being explosive:

Code: Select all

x = 33, y = 23, rule = B3-n/S2-n3-n4-na
12bo10bo6bo$3o8b2o9b3o4bobo$11b3o8bobo4bob2o$23bo8bo17$16bo$15b3o$15b
3o!
[[ RANDOMIZE ]]

This is a good rulegolfing starting point; I might look at it more later.

Edit: Adding B8 gets you a cool failedrep:

Code: Select all

x = 3, y = 3, rule = B3-n8/S2-n3-n4-an
3o$obo$3o!

I've started making a user page compiling many cool/useful user pages, which can be viewed here. You can make suggestions here or on the discussion page.

Hopefully this isn't made redundant by something like this already existing.
