I third it. However, remember to post your non-Life questions in the Other Cellular Automata forum.

Code: Select all

x = 5, y = 9, rule = B3-jqr/S01c2-in3
3bo$4bo$o2bo$2o2$2o$o2bo$4bo$3bo!

Code: Select all

x = 7, y = 5, rule = B3/S2-i3-y4i

Thanks! I haven’t thought enough when I posted the thing. This is obviously a pattern.... hence I thought it should go in Pattern. But maybe someone can help me shop this to OCA? @dvrgn

Done (by dvgrn, not dvrgn, though.)

This pattern is bound to settle into an oscillator at some point, but it's not clear that a browser-based oscar.py is going to help find out when. It might have to run billions or trillions of generations before the first repeating phase shows up. Here's the pattern after ten million ticks:

I ran that for another 2.5 million ticks with oscar.py without finding a repeat. So it probably hasn't settled into oscillation as of T=10 million ticks, or if it has, the period is something over a million (oscar.py only finds a length-N repeat by running N ticks, if it gets really lucky and the first tick is a hash minimum -- but it's guaranteed to find a length-N repeat by running 2N ticks).

in case anyone wants to start from here to look for an upper bound, here's the pattern at T=12,544,021 where I stopped running oscar.py:

The last time I worked on a question like this, the answer turned out to be 21,858,777,744 ticks -- which is not a number that can be found in a reasonable time with even a non-browser-based version of oscar.py, let alone one associated with LifeViewer. The oscar.py method is time-consuming, because it ends up taking the hash of every tick of the pattern starting from T=0. There are simpler but less universal period-finding methods that can be much more efficient.

-----------------------------------------

A rough summary of a good method when you don't even know the order of magnitude of a pattern's eventual period:

Step 1: run pattern with the fastest possible algorithm for almost forever (i.e., until you're thoroughly bored, and just before you stop caring what the pattern's eventual period is anyway).
Step 2: Take hash of resulting pattern.
Step 3: Run pattern one tick at a time and wait for the same hash value to appear.

If no hash value duplicate appears, you didn't wait long enough, and therefore your current combination of computer hardware and patience is not sufficient to find the eventual settled period of the pattern in question.

If you do see a duplicated hash value, then your original wait was long enough (probably, unless you've happened upon a hash collision, which would almost be more interesting than an actual match!). You now have an upper bound on both the period and the settling time. Upper bounds are incredibly useful things -- you then know that you'll be able to find exact answers with an amount of work that's in the same order of magnitude as the CPU time you've invested already.

The problem with putting the oscar algorithm into LifeViewer is that LifeViewer doesn't have anywhere near the fastest possible algorithm for simulating patterns. This means that the majority of problems along these lines that are solvable with current technology, are not solvable using a LifeViewer/browser-based solution... which calls into question whether it would be worthwhile to create that kind of solution in the first place.

To explore such rules in more detail use smaller worlds. 50x50 works well for this rule.

See "Walled Cities":

for more beautiful long period oscillators.

@dvgrn: Many thanks for those suggestions! The outline of this algorithm looks quite reasonable! Maybe we should produce a bash script to do this more systematically?

@bprentice: I totally agree that I should reduce the grid size. I was actually studying the distribution of lengths of transients myself a long time ago and this maybe a good time to pick it up again. However I do remember the conclusion that: interesting rules has diverging transients whereas the opposite isn’t very true...

In any case, let me finish my master thesis first....
