Me too. At that many generations it's using 30 bits and the hash is only 32 bits so will likely need widening.

I assume this can be done dynamically as the number of required bits increases? Would there be any performance benefit to, say, starting out with 16 and increasing that to 32 if this is considered to be required?

Somewhat related: it may be interesting to have debug information about Identify displayed during the identification process if showtiming/extendedtiming is on but I don't know if that'd be the backlogged "Identify improvements" thing all over again.

For timescales such as this it may be worth reducing the bounding box as much as possible. Using plane boundaries may improve things (unless bounded-cells cost more to draw to the point where it slows things down more than the decreased bounding box size would increase speed):

Code: Select all

x = 48, y = 2, rule = MarBlocks-5-rep:P48,2

Perhaps this would be twice as fast still:

When using the Neighbour shader, going to Help > Info > Cells correctly lists the shader used as "Neighbour Count", however it then incorrectly provides the Cell Age colours instead despite these not being used at all here. Can this be fixed so that the Neighbour Count colors are listed here instead?

Use Save Pattern on this - it will correctly save an empty pattern, but the x and y values saved will not change. If the pattern is then reopened and saved a second time, the x and y values will be correctly set to 1, which should happen the first time around.

Code: Select all

x = 10, y = 10, rule = B/S
2o6b2o$2o6b2o7$2o6b2o$2o6b2o!
[[ STARTFROM 1 ]]

Also, in this pattern, they are saved as 2 the second time instead, when they should instead be 1 (empty space's evolution never matters if you only use M0 or M15):

Code: Select all

x = 10, y = 10, rule = M0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

When a pattern's period is recognised, and the period is lower than a given value (e.g. 1000), can the "Oscillator/Spaceship period" notice and delay be skipped? The delay this message produces is often greater than the actual time needed to calculate everything (which often comes out to less than 0.1 seconds), so having it be completely absent for sufficiently low periods seems like the better option, as low-period objects seldom require large amounts of time for statistic computation.

Code: Select all

I've always wanted to know what these permanently-dead cells out of bounds represent, by the way; normal cell birth can never turn these on, and they appear to be much the same across all bounded grid types.

The behaviour is different in the general-range algorithm, where births never happen, and cells never age. This makes me wonder: could we improve performance in the range-1 algorithm by not ticking any cells outside of bounded grid boundaries, for either evolution or ageing?

The second of these is corrected to K10,10*+1, but the first is considered invalid. Since there's only one valid place to put the * twist indicator, I'd have expected that this would be corrected and loaded as K10*+1,10 instead. Can this be made to happen for cases like these? I run into this every so often when running patterns on shifted Klein bottles and it does get slightly irritating.

Since we no longer have an upper limit for periods: in what cases is "Nothing Identified" supposed to appear? Using Identify on this causes it to appear, though this relies on a bug. I don't know why it happens, since T doesn't get very high.

It may be a good idea to assume "nothing identified" as soon as some nonzero cells are deleted due to hitting the edge. That means the actual pattern would evolve differently on the (infinite) square tiling, and how exactly it would evolve cannot be determined by trying to evolve the damaged version further.

It may be a good idea to assume "nothing identified" as soon as there is some trickery with LifeViewer scripts that contradicts the prescribed rules of the CA. After a PASTET of some sort, it would be reasonable to expect "nothing identified", it cannot be a working oscillator, it cannot be a working spaceship, it's some "non-CA trickery".

It may be a good idea to assume "nothing identified" for probabilistic variations. If the same pattern can evolve differently when you run it twice in a row, there's nothing to identify.

In such cases, I expect there would be often annoying differences of different kinds between what happens in the "theoretical partial completion" and what happens in an actual completion. The spark would be different, there would be massive sparkers added affecting the output of Identify, there could be a different arrangement of hassled objects that is considered to be a variant/completion of the same idea, and so on, and so forth.

You could manage to find an "alien completion" for some CGoL partial. If it works according to some CA rules then it can make sense to "Identify" it. Again, it wouldn't work in CGoL, and another completion that would work in CGoL would result in a different "Identify" output.

All things considered, I would prefer blocking Identify as soon as there is some automatic pasting or similar "scripting trickery". Either it follows the rules (and therefore exists as a CA reaction in a known way), or it doesn't follow the rules.

If we Save Pattern, the bounded grid on the first pattern is converted to the canonical format K20,20*, but the second is left as is.

Code: Select all

In both cases, there should only be one history state, at the lowest level (rather than the 3 in Standard and 63 in Pro).
Code: Select all
x = 4, y = 2, rule = B2/S
o2bo$b2o!
[[ LAYERS 10 HISTORYSTATES 1 GRID COLOR DEADRAMP White ]]

This seems to happen even if we set HISTORYSTATES to 0. LifeViewer Standard still works correctly and has no such trail.

Code: Select all

x = 4, y = 4, rule = B367/S23
bobo$o2bo$b3o$2bo!
[[ STARTFROM 32 HISTORYSTATES 0 LAYERS 10 GRID ZOOM 16 ]]

Code: Select all

x = 4, y = 4, rule = R1,C2,S2-3,B3,6-7
bobo$o2bo$b3o$2bo!
[[ STARTFROM 32 HISTORYSTATES 0 LAYERS 10 GRID ZOOM 16 ]]

After this gets fully identified (which takes a while), the framerate will be very low, even when playback isn't happening. Going back to T=0 will fix this, even if we view Last Identify, but I still don't think the framerate should be as low if nothing is happening and there nothing expensive to draw.

Code: Select all

x = 1, y = 1, rule = R500,C2,S,B1,NM

Fixed, thanks.

muzik wrote: March 19th, 2025, 6:36 pm Before this accident happens: can a prompt be displayed when trying to close a tab or browser window in which Identify is happening?

No, but I've been considering copying a checkpoint to the clipboard every so often.

Now 12.4B...

muzik wrote: March 20th, 2025, 3:51 am Is there a way I can dedicate more computer resources to LifeViewer (presumably an offline downloaded version) as to hopefully increase Identify's speed and obtain a result faster?

No.

muzik wrote: March 20th, 2025, 3:51 am If we Save Pattern, the bounded grid on the first pattern is converted to the canonical format K20,20*, but the second is left as is.

Fixed, thanks.

muzik wrote: March 20th, 2025, 3:51 am It may be worth converting these two to the same thing when saving patterns, as they're functionally identical

No. Other than making things canonical it's unexpected to have them changed.

muzik wrote: March 19th, 2025, 3:44 pm Very surprised I never found the following exploit before now. (Can we get "ability to draw outside of bounded grid" in LifeViewer Ultra, by any chance?)

Fixed. (No, it's way too expensive).

Identifying the first pattern will block identification of the second pattern:

Code: Select all

#CXRLE Pos=-238,-238
x = 4, y = 4, rule = B2a3i/S
2b2o2$o$o!
[[ MAXGRIDSIZE 9 ZOOM 8 ]]

Code: Select all

x = 12, y = 12, rule = B2/S:S20

According to this post we could be here for a while: the upper bound for the period is 238 trillion (though it's more likely to be a factor of this).

If we're dealing with timescales such as this, could the T counter be made to display such values accordingly (up to 1 quadrillion)?

Code: Select all

#CXRLE Gen=999999999900
x = 3, y = 3, rule = B3/S23
o$obo$2o!
[[ AUTOSTART SHOWGENSTATS TRACK -1/4 1/4 LABEL 1 -3 32 "#I" LABELTRACK -1/4 1/4 ]]

Could we also improve Identify's performance if we can somehow promise that a pattern will never escape a given bounding box (e.g. by encasing the thing we're identifying in a bounded grid)?

This still appears to happen in build 1297.

Here's a new test case for something mentioned previously: the FPS will still be low after identification completes.

Code: Select all

x = 1, y = 1, rule = R500,C2,S,B1:P13383

For some reason, loading this in LifeViewer Pro will display an out of memory error, even though no playback happens:

Code: Select all

x = 1, y = 1, rule = R1,C2,S,B:P12000
