Thanks!

Another silly 4-cell gun precursor in rule StateInvestigator.

#CXRLE Pos=10,0
x = 25, y = 25, rule = LifeInvestigator

Wow, it feels surreal to be back after nearly a decade! I'm delighted to see this is still the same community I knew, just with some impressive upgrades along the way. It's like reuniting with an old friend who's somehow gotten even better with age.

Welcome back after 9 years!
Also, I can't run your pattern. Can you provide RLE so I can run it in LifeViewer?

Sorry, my fault.. I posted an .mc file.

Code: Select all

#CXRLE Pos=-20,-10
x = 20, y = 20, rule = LifeInvestigator

Silly, period-220, 2-cell gun in LifeInvestigator rule. Probably already known.

Good question. It turns out that I never ventured into the wilderness of 40-bit 1-cell thick patterns.

Er... None that I know of.

Thank you very much!

dvgrn wrote:It's not exactly a trick, but you would have to write a separate LifeHistory rule for each base rule -- LifeHistoryB38S238, etc. Unfortunately it's a bit more complicated to write LifeHistory versions of rules with more possible B and S options.

Thank you for your detailed answer.

I'm not sure if the edges of the block-laying object could be made stable... It's probably too fast... Fail.

x = 97, y = 6, rule = B3/S23

Clean, stupid almost wick. Hopefully, it could be made to burn at one end. Probably already discovered.

Hello to all:

Just a quick question. Is there a trick to get the LifeHistory functionality for an arbitrary cellular automaton e.g. B38/S238?

I'm trying these two commands successively:

g_setrule("B357/S238");
g_setrule("LifeHistory");

But it seems as if LifeHistory is hardwired to B3/S23 ...

Hey, such a sweet idea! Thank you!

DivusIulius

Just a quick question: Is there a way in Golly to get Random Fill probabilities inferior to 1% with/without scripting?.

Thanks in advance.

Three-glider mess takes 8,140 generations to stabilize. 26 gliders are produced...

x = 13, y = 12, rule = B3/S23

And finally, the smallest (in terms of bounding box) 4-cell thick pattern which produces a LWSS:

Code: Select all

x = 4, y = 4, rule = B3/S23
b3o$3bo$2b2o$3o!

And the smallest (in terms of bounding box) 3-cell thick pattern which produces a LWSS:

Code: Select all

x = 5, y = 3, rule = B3/S23
b4o$b2obo$2o2bo!

DivusIulius

Another oldie... Smallest (in terms of bounding box) 2-cell thick pattern which produces a LWSS:

Code: Select all

x = 7, y = 2, rule = B3/S23
2bobobo$7o!

DivusIulius

Old and useless... (Almost)-smallest (in terms of bounding box) patterns (after the glider, r-pentomino and their 3 x 3 predecessors), which produce glider(s). http://www.torontomazda3.ca/forum/images/smilies/facepalm.gif

x = 5, y = 2, rule = B3/S23

x = 5, y = 2, rule = B3/S23 ...

I'm going to spam patterns that produce two somewhat closely-spaced gliders :lol:

x = 4, y = 6, rule = B3/S23
b2o$o2bo$ob2o$o$b2o$2bo!

x = 6, y = 8, rule = B3/S23
2o$2o5$b3o$3b3o!

x = 5, y = 9, rule = B3/S23

x = 9, y = 5, rule = B3/S23
2o$2o3b3o2$5bo2bo$6b3o ...

DivusIulius

Another useless one: how to arrange two R-pentominoes so that they produce the maximum population of 2818/2814 cells.

Code: Select all

x = 5, y = 25, rule = B3/S23
2o$b2o$bo20$3bo$2b2o$3b2o!

Edit: It takes 9,496 generations to stabilize.

Thank you very much!

I was very surprised to see so many pulsars in the final output, by the way -- until the extra "8" in the rule string caught my eye!

Thanks... D'oh! I too noticed the pulsar anomaly but I didn't realize I was pasting a Pulsar Life pattern! http://www.yuuguu.com/images/emoticons/yuuguudefault ...

Four-glider mess takes 22,502 generations to stabilize.

77 gliders and 1 lightweight spaceship are produced...

I'm not sure if the gliders come from infinity. How might I verify this?

Hmmm... homework...
