PHPBB12345's pattern is a predecessor of my pattern.

Should their be a rule that you cannot post a pattern that is a predecessor of the starting generation of an earlier pattern?

I don't really think that's necessary. It'd be nice to at least discourage posting predecessor patterns, but I'm afraid that making it a rule might make it difficult to progress if we hit a number where finding a pattern with that lifespan is very difficult.

I was going to post gen 5 of that at 50, but I missed the opportunity. Couldn't resist getting it into this thread somehow.

I don't have a problem with allowing predecessors either - but it's nice if some other quality is considered as well as just being a predecessor.

There's quite a way to go before you hit that point, though. Check out the two pieces of Andrzej Okrasinski's die658 diehard, for example -- Golly's Patterns/Life/Miscellaneous/die658.rle.

The top part could be borrowed for patterns stabilizing anywhere from T-minus-81 to T-minus-73:

Code: Select all

x = 20, y = 9, rule = B3/S23
bo$obo$o2bo$b2o10bo$10b4o3b3o$9b3obo3bo$9bo3bo3b2o$9b2o8bo$11b3o!

The other half takes 236 ticks to stabilize, and stays below 20x20 the whole way, so you can borrow a phase from it any time you get into trouble --

Code: Select all

x = 14, y = 19, rule = B3/S23

And of course the original diehard is 20x20, and lasts 658 ticks. That was a random result from a long-running soup-search project.

A fairly minor hack of apgsearch code would spew out 16x16 soups that stabilize in any reasonable number of ticks that you might care to name -- with "reasonable" probably being anything up to five or ten thousand, if you're willing to be patient and let the search run for a while.

Rules added from Alexey_Nigin (Thank you!)

Firstly, limit the bounding box to 20x20 or something. Otherwise one could post a long diagonal line. Limiting the number of cells is not an option, since one could post a glider hitting a faraway block.

Secondly, either explicitly disallow infinite growth or provide criteria for when an infinite growth pattern "stabilizes".

Thirdly, make it so one can't just post the best methuselah known to date and spoil all fun. To accomplish this, you may say that every pattern should stabilize in exactly one more generation than the one before it.

But then there are only 2^400 possible patterns, and eventually we'll run out!

You don't need to overquote for that. It's too spammy. Besides, the maximum bounding box will expand one that happens. We won't get to that limit anytime soon, so worrying about it isn't too useful. Speaking of useful, 65:

I think the rules should be more specific.

Firstly, limit the bounding box to 20x20 or something. Otherwise one could post a long diagonal line. Limiting the number of cells is not an option, since one could post a glider hitting a faraway block.

He said "until bounding box grows too big", and his patterns are still within 20x20.
