Hey, technically, if we can synthesize something, shouldn't that mean it's instantly natural? because gliders spawn naturally and COULD synthesize what ever it is.

The definition of "natural" is a bit fuzzy, but an object is generally said to be "natural" if it has been seen in the ash of a random soup.

On "fuzzy": if one believes that the truth of such statements as "X is natural" for a given pattern X does not change over time, then a pattern was already natural before the soup it arose from was found (we merely didn't know it yet). And given that every pattern could itself be produced by chance as a random soup (the odds are, in fact, exactly as large as the odd that any other given random soup of the same size is generated), it follows that all patterns are in fact natural. (This is basically the same argument you're making, except without the intermediate gliders.)

Of course this isn't the usual meaning of "natural". The actual meaning is best characterized as "as long as we don't think about it too much we all know what it is", so we do indeed try not to think about it too much. (See what I mean about "fuzzy"?)

Long story short, no, synthesizable objects are not automatically natural unless and until they actually appear in a random (a priori asymmetric) soup's ash.
There is no way that this is the highest possible trivial oscillator yet. but if it is, I won't know what do do with myself...
All oscillators above a certain period (43) are trivially constructible as a glider loop. (The lower bound is 43 because that's the recovery time of the snark, the fastest known glider reflector.)

So constructing a (say) period-59219161 oscillator is as easy as setting up some snarks and putting a glider loop between them -- just make sure the gliders are sufficiently far apart from each other. (The higher the desired period, the bigger and sparser the entire loop will have to be.)

Nick Gotts gave a paper at the CA98 conference that dealt with naturalness. I will try to reconstruct some of the basic ideas from memory, although my understanding is fairly imperfect.

Assume that the initial universe is seeded with random cells, with a probability p (where p is close to 0) that any given cell is alive. Random bits occur with probability O(p), close bit-pairs with probability O(p^2), triplets with probability O(p^3), etc. Since all triplets either die or form blinkers or blocks in one generation, these are called "blonks". The first interesting patterns occur at O(p^5) (gliders, and R-pentominos that also make gliders). Arbitrary n-bit objects and patterns occur with a probability at most O(p^n), although if they can be synthesized easily, say, from g gliders, they would be O(p^5g), if 5g<n. By using similar projections, one could determine how large an area you would need to examine before switch engines were likely (e.g. O(p^11)), or other puffers, guns, or breeders, etc. (For example, if p=1/1000000, a million by a million square would likely hold one bit-pair, and a trillion by a trillion square would likely hold one beehive, pond, or traffic light. A switch engine would be expected somewhere in a square around 3e30 on a side. P must be kept very small so that O notation holds - i.e. no reasonable number of copies of an object of one rarity will make it less rare than any object of a lesser degree of rarity.)

This sort of pattern is more appropriate for the sandbox. While I'm sure that this exact construction has not been made before, these oscillator combinations don't really represent new technology.

LifeHistory provides a very useful way to visualize life patterns. It is used commonly throughout the forums, and I doubt that will change any time soon.

If you want to change a "simple" LifeHistory pattern (one with only green and blue cells) to standard life, one way is to do the following:
1. Paste the LifeHistory pattern into Golly.
2. From the menus, select Control->Set Rule.
3. Change the algorithm to "Generations".
4. In the box labeled "Enter a new rule:" write "012345678//3" and press "OK".
5. Run the pattern for one generation (this will get rid of the "blue" cells, which will have changed color when you changed the rule).
6. Change the rule back to standard life (use "select a named rule" in the change rule dialog).
The "better" way to change LifeHistory to Life would be to use the change-state.py script in Golly. To do this, you need to get Golly to be able to run python scripts. Once you've done this, you can run change-state.py by going to Help->Online Archives and selecting Golly Scripts Database and then change-state.py. In the dialog that pops up, enter "2 0" to change state 2 (blue cells) into state 0 (black/empty cells). Finally, change the rule to standard Life.

Hello 83bismuth38,
It seems like you are experimenting with well-known patterns.
Yes, I appreciate your enthusiasm in Life, but you might want to improve your knowledge on these patterns. No offense, but the patterns you are posting are not discoveries. Look at the oscillator you posted. Yes, the period is high, but they are trivial as they do not have a single cell that oscillates the entire period. Take this, for example. It is a non-trivial oscillator based on an interaction with sparks:

Code: Select all

x = 16, y = 23, rule = B3/S23

This, however, is trivial: Code: Select all x = 41, y = 34, rule = B3/S23 3bo2bo$7bo$8b2o$2bob2o6bo$2bo2bo3bo$bo3bob3o$o11bo$3b3obo3bo$3bo3bo2bo$o6b2obo$3b2o$5bo$6bo2bo2$10b2o8bobobo3bobobo3bobobo$8bo4bo$7bo6bo9bo

Because there is no cell that oscillates at p360.

Assume that the initial universe is seeded with random cells, with a probability p (where p is close to 0) that any given cell is alive. Random bits occur with probability O(p), close bit-pairs with probability O(p^2), triplets with probability O(p^3), etc. Since all triplets either die or form blinkers or blocks in one generation, these are called "blonks". The first interesting patterns occur at O(p^5) (gliders, and R-pentominos that also make gliders). Arbitrary n-bit objects and patterns occur with a probability at most O(p^n), although if they can be synthesized easily, say, from g gliders, they would be O(p^5g), if 5g<n.
I think Nick Gotts' idea was that most objects will be produced by an 'inverse slow salvo' comprising a single R-pentomino and some distant blonks. Everything expressible in this way (including everything with a glider synthesis) would still be O(p^5).

It's a dart, originally found by David Bell in 1992. Usually -- but not always, see copperhead and loafer -- things that can be discovered by a short search with a known utility have been discovered before, most likely multiple times.

Is this thread also for rules other than conway life? Discoveries in other rules generally end up on the Other Cellular Automata board, under Thread for Your Accidental Discoveries that Aren't in CGOL or Miscellaneous Discoveries in Other Cellular Automata. I don't think we have an exact match for "unsure discoveries". I suppose rediscoveries are an awful lot less likely in other CAs -- it's mostly only B3/S23 that's been investigated obsessively for 47 years...!

May or may not be known. Interesting! I don't think that one's known. It looks like it uses a similar mechanism to the bilateral head-on collisions seen in Double X. Is that how you found it? It looks like it could be used to reduce pseudo-period guns in the gun collection...

Is that how you found it? I actually saw the sparker in jslife/osc/o0006-spark.lif and wondered what the spark was for. So I tried a LWSS, and found that. There are likely sparkers of other periods that work as well.

The Karel's p15s shown here almost work, and p40 traffic jam oscillators work but don't fit: Code: Select all x = 45, y = 45, rule = B3/S23 11b3o$10bo3bo4bo$10bo3bo3bobo$11b3o4bob2o$17b2o3$17b2o$11b3o4bob2o$10b
