2obo!

The initial linear delay is increased by 2 salvos. In the upper left I figured out how to suppress the big spark that results from adding the eater-with-tail. On net it gives the same result as just adding an eater, but I spent all day trying to suppress that spark.

b3s23love: The search program I use was written by me over the last two months from scratch. I didn't even copy from any of my old code. In general I have to edit the source code, compile, and debug (and there are always bugs) for each new thing I try to search for.

Have a happy day,

-Tim Coe

One more first sawtooth pull before the first fuse is lit:

EDIT AGAIN:

The wrong phase on the second fuse was backed up into space dust. Replaced with a compatible version of space dust that is backed up from the correct phase of the second fuse (the different lighter works with the tub configuration).

Very nice! I've been looking at this area here, and noticed that if an extra eater head is attached to one of the block destroyers, then it produces a mild spark to the west:

Could we place some bait still lifes in this area to, when triggered by this spark, edge-shoot another block-destroyer of some type (maybe a loaf or tub?) onto the correct lane? The search space is pretty large so it doesn't seem too implausible. This will give another level to the inner tower.

One more first sawtooth pull before the first fuse is lit:

There was a single-cell bug in one of the blobs of space dust which caused the final shutdown to fail. Here's the corrected version, colourised:

There was a single-cell bug in one of the blobs of space dust which caused the final shutdown to fail. Here's the corrected version

Speaking of which, can I take a look at the self destruct sequence?

[moebius]

Hi All,

I appreciated Calcyman's suggestion to use the empty space to put some tubs back. I investigated this and it turns out that triggered still lives that deposit something a distance away, while avoiding obstructions are extremely rare. This is due to the explosive nature of anything that moves a significant amount of distance.

Our current mighty fine tubs2 are pitch 3 diagonals. I decided to search for pitch 4 still lives that deleted to 2 pulls. I found them, but they tend to be explosive. So I also searched for pitch 5 still lives that had less explosive operation and also deleted 2 pulls.

The following under 10000 area diehard has a lifespan lower bounded by 121 ^^ (121 ^^ 9):

I have to thank Toroidalet for pointing out the "stick the nose on" technique for shutting down the first sawtooth. This makes it very easy to check out the behavior of both the the first sawtooth and the second sawtooth.

Albert ArmStain: I will post a variety of shutdown examples in the next few days.

Have a happy day,

-Tim Coe

Also, some yellow tubs were shifted to add an eater (it was very lucky that the eater barely misses the two boats with tails).

EDIT: And some lime tubs were added. They don't delay the fuse, but they still require two block pulls after it to clean up. The tub catalysis was another stroke of luck.

I have to thank Toroidalet for pointing out the "stick the nose on" technique for shutting down the first sawtooth. This makes it very easy to check out the behavior of both the the first sawtooth and the second sawtooth.

This may be, in all seriousness, my most significant contribution to the diehard project.

Also, some yellow tubs were shifted to add an eater (it was very lucky that the eater barely misses the two boats with tails).

EDIT: And some lime tubs were added. They don't delay the fuse, but they still require two block pulls after it to clean up. The tub catalysis was another stroke of luck.

Impressive! This has a lifespan slightly greater than:

121 ^^ (121^121^121^121^121^121^121^121^121^1356648129958673823266622201465466300)

which is in turn greater than 11 ^^^ 3 in Knuth's up-arrow notation. (11 ^^^ 3 is a tighter lower bound than 121 ^^ (121 ^^ 10), as well as being more succinct. Each time we add an extra block-destroyer, that '11' will increment, until it gets to 25; the pattern stops there because 26^26 is larger than the number of loaves produced by the first fuse.)

[Entity Valkyrie 2]

121 ^^ (121^121^121^121^121^121^121^121^121^1356648129958673823266622201465466300)

that is 100^^(100^100^100^100^100^100^100^100^100^5345A5A5A5A5A5A5A5A5A5A5A5A5A5A5A3A) when the numbers are re-written in base eleven

Probably won't be an improvement anyway, but could we do something like this:

Code: Select all

x = 112, y = 89, rule = B3/S23Super

Hi All,

On my first post to this thread I mentioned that I tried to start the diehard by sending a glider over the top and that I couldn't get it to work. I found a way to make that work:

The key was that the other Simkin gun in the upper right is shut down, which allows freedom of passage of the lighting glider.

The lighting glider must be the correct phase modulo 120 or it will not work (the correct phasing to the fuses must be maintained).

This gave me 6 additional salvos of delay. 3 salvo delays came from the time it took for the lighting glider to travel. The other 3 salvos of delay came from the additional space freed up by shutting down the Simkin gun (one of which was very difficult to find).

I decided to try and free up even more space by shutting down all the Simkin guns. The space dust was expanded in the lower right to get this to work:

I decided to try and free up even more space by shutting down all the Simkin guns. The space dust was expanded in the lower right to get this to work:

Code: Select all

x = 114, y = 91, rule = B3/S23...

112x89 is well within the 10,000-cell bounding box limit, but 114x91 will need a bit of work.

In terms of getting the delay before gliders are emitted to be as high as possible, it just occurred to me to wonder whether there might be a way to do something other than dropping in objects that get gradually but steadily eroded away. How much more room would be needed to get some kind of crystal growth started, and convert it to crystal erosion near the Simkin gun with the usual eater so that the glider stream clears out the newly created crystal and picks up the next crystal seed in a series?

Then the trick would be to pack as many crystal seeds onto the output lane as possible.

[b3s23love]

Congratulations on the even more improved diehard! I think we're close to optimal, so I'd like to ask: what such (not-so) Pointless Optimisation Game would we play (I mean one with lots of mechanisms and improvements, absurd numbers, etc; like the engineered diehard one)? It was very fun to see the progress, and participate in some of it.

In terms of getting the delay before gliders are emitted to be as high as possible, it just occurred to me to wonder whether there might be a way to do something other than dropping in objects that get gradually but steadily eroded away. How much more room would be needed to get some kind of crystal growth started, and convert it to crystal erosion near the Simkin gun with the usual eater so that the glider stream clears out the newly created crystal and picks up the next crystal seed in a series?

Then the trick would be to pack as many crystal seeds onto the output lane as possible.

Would you like to present an example visualisation of the mechanism and how would it work? Will it be like in this post by Dean Hickerson? EDIT: I don't think it's possible in the limited space, though.

In each of those the number of gliders consumed grows linearly with the available length. But with enough room alongside we can achieve quadratic growth by using crystallization and decay. In this pattern the glider stream repeatedly hits a snake, starting crystal growth. The growth is stopped upstream by some blocks; 3 blocks stop 9 crystals:

Also, what ideas could we have for the smaller diehards (16x16, 32x32, 50x50, 75x75, etc)?

Hi All,

On my first post to this thread I mentioned that I tried to start the diehard by sending a glider over the top and that I couldn't get it to work. I found a way to make that work:

The key was that the other Simkin gun in the upper right is shut down, which allows freedom of passage of the lighting glider.

The lighting glider must be the correct phase modulo 120 or it will not work (the correct phasing to the fuses must be maintained).

I can delay it by 600 generations (5 periods) with help from a great-great-great-grandparent of Dean Hickerson and a block. Note that the spark gets uncomfortably close to that block-on-eater; it's very fortunate that the reaction manages to fit so snugly:

There's definitely room to do more antics similar to those in toroidalet's post, especially now that the lighting glider originates from within that unused empty space.

[squareroot12621]

…I think we're close to optimal, so I'd like to ask: what such (not-so) Pointless Optimisation Game would we play (I mean one with lots of mechanisms and improvements, absurd numbers, etc; like the engineered diehard one)? It was very fun to see the progress, and participate in some of it.…

Since a diehard is a pattern that ends with a population of 0, I think it should be:

What is the largest population attainable by a starting pattern that fits in an area of at most 10,000 cells?

It's also kind of fitting, because it's been exactly 1½ years after I posted this topic.

I'm sure Moebius can use his program to find crazy still life turners that make it last much longer.

Can anyone get a glider to shoot towards the light blue during the cleanup, if so we could replace that with a crabstreacher plus some gliders to provide a single-glider cleanup. I was never able to get the glider to form though

[b3s23love]

This one has an extra 144 generations over Calcyman's, and I rephased the queen bees by 6 generations to compensate (144+6=150=5*30; we don't need to alter the fuses because 144=6*24), allowing for two more pink delays (another 240):

This was actually mine and Calcyman’s. APG made the optimisation, I incorporated it into the main diehard.

I'm sure Moebius can use his program to find crazy still life turners that make it last much longer.

Maybe just ask him for the programs that he uses for searching?

I'm not sure what this means. Are you suggesting that one of the salmon turners would release a glider in the direction of the northwest corner( where the glider bounces around before hitting the far eater), which would then destroy a crabstretcher? Unless that sent a glider back, it wouldn't even increase the lifespan at all (the gliders take longer to hit the 58P5H1V1), and even then it would not be worth it (it would multiply the lifetime by a small constant).

This was actually mine and Calcyman’s. APG made the optimisation, I incorporated it into the main diehard.

Sorry about that.
I was specifically referring to the northwest corner and the state-19 glider bouncers rather than the diehard as a whole, which was probably not obvious. Also, I had independently added it to the diehard without being aware of your contribution.

Maybe just ask him for the programs that he uses for searching?

I don't care enough about crazy still life turners. I was just pointing out potential improvements.


Also, about the highest population pattern, it would probably look a lot like the diehard, but the other ends on the guns would be open and it would last longer.

[dvgrn]

Congratulations on the even more improved diehard! I think we're close to optimal, ...

Heh. Nobody has dared to try a complete redesign from the ground up yet, using everything that has learned along the way. I wonder what a new build would look like if people aimed for, say, 80*125?

Also, about the highest population pattern, it would probably look a lot like the diehard, but the other ends on the guns would be open and it would last longer.

Seems like that challenge would need a more specific problem statement (and a separate thread).

It needs to say something like "largest possible finite population", right? -- to prevent the prize from being taken by a plain old spacefiller predecessor with optional HWSSes and gliders and suchlike packed around it. Maybe something more limiting would be better, like "largest possible population for a pattern where the bounding box eventually stops growing."

EDIT: Yup, letting stuff just wander off to infinity just seems too messy -- maybe better to not allow that in a highest-population contest. Or at least not in every highest-population contest.

You're right about the finite population thing, but "where the bounding box eventually stops growing" seems to disqualify glider-emitting patterns; was this intentional?

Also, what ideas could we have for the smaller diehards (16x16, 32x32, 50x50, 75x75, etc)?

Here's a stamp collection of my best diehards for most square sizes up to 31x31. Maybe someone will find it useful, either for some of the components or just as a goal to beat. I had some larger ones in the collection, but Moebius's recent 32x32 with a lifetime of 1120271 makes those obsolete. Probably the same method can be used for somewhat smaller cases.

Sorry about that.
I was specifically referring to the northwest corner and the state-19 glider bouncers rather than the diehard as a whole, which was probably not obvious. Also, I had independently added it to the diehard without being aware of your contribution.

Thank you! Anyway, I think your diehard is an improvement over mine.

Congratulations on the even more improved diehard! I think we're close to optimal, ...

Heh. Nobody has dared to try a complete redesign from the ground up yet, using everything that has learned along the way. I wonder what a new build would look like if people aimed for, say, 80*125?

I don't think we could fit a third sawtooth in 80x125. How would that work?

Since a diehard is a pattern that ends with a population of 0, I think it should be:

What is the largest population attainable by a starting pattern that fits in an area of at most 10,000 cells?

I thought of something different, unrelated to this project.

It's also kind of fitting, because it's been exactly 1½ years after I posted this topic.

I think you should also be credited for this, because you created this thread and you started the research.

[wirehead]

I think the next step would be to increase the bounding box to 40,000 cells and then do tetrations on each corner that all feed into each other, so it would be 8 up-arrows in the final function.

Just plugging this suggestion again... or some variation of it. I see you all are trying to really increase the delay in the top left corner, so why not put a sawtooth there with a few still lives so it will go a few rounds of the sawtooth, then have it start the simkin guns?
