And where is your program's code?

Posted: **October 11th, 2015, 4:33 pm**

I don't know if my code is this useful. dvgrn told me not to put every script I make.

Posted: **October 11th, 2015, 5:31 pm**

I deleted it and changed it for a more practical Golly script. Here is the current state of the golly script:

import golly as g
import random as r

coilsinp = g.getstring('Python list of induction coils to use?', '', 'Induction coils')
layerinp = g.getstring('Maximum number of induction coils inducting each other?')
mcoilinp = g.getstring('Maximum number of induction coils?')

if coilsinp == '':
	coillist = [g.parse('2o$2o!'), g.parse('bo$obo$bo!'), g.parse('b2o$o2bo$bobo$2bo!'). g.parse('b3o$o2bo$bobo$2bo!'). g.parse('3o$o2bo$b2o!'), g.parse('3o$o2bo$2b2o!')]
else:
	coillist = coilsinp.split(',')
	
if layerinp != '':
	maxlayers = layerinp
else:
	maxlayers = 3
	
if mcoilinp != '':
	maxcoils = mcoilinp
else:
	maxcoils = 12

dpa = (maxcoils - r.randint(0, maxcoils))
tosel = g.getcells(g.getselrect)
dasel = g.getselrect
g.addlayer()
g.putcells(tosel, 0, 0)
g.select(0, 0, dasel[2], dasel[3])
while true:
	
	while dpa > 0:
		g.putcells(coilsinp[r.randint(0, 5)], r.randint(-11, (dasel[2] + 11), r.randint(-11, (dasel[3] + 11))
		dpa -= 1
	
	if g.getselrect == g.evolve(g.getcells(g.getselrect), 50):
		break

Still don't support welds or extensions and have some weird error I can't fix.

Posted: **October 11th, 2015, 6:25 pm**

Please help! This is an important script as I have two Eater 2s I have been having difficulty to weld!

Code: Select all

x = 11, y = 8, rule = B3/S23
2bo$bobo2bob2o$bobob2ob2o$2ob2o$5b2ob2o$2ob2obobo$2obo6bo$9b2o!

Posted: **October 11th, 2015, 6:35 pm**

Here's a solution:

Code: Select all

x = 10, y = 11, rule = B3/S23
2b2ob2o$bobobo2b2o$bobo2bob2o$2ob2obo$6bob2o$2ob4obo$2obo4bo$5b2ob2o$
6bobo$6bobo$7bo!

Posted: **October 11th, 2015, 6:44 pm**

Ooh thanks! But still I need that script work as it will be very useful further, for it to generate its own induction of things like:

Code: Select all

x = 6, y = 8, rule = B3/S23
4b2o$3bobo$3bo$3bo$2bo$2bo$obo$2o!

Posted: **October 11th, 2015, 6:56 pm**

Not sure how to do that, but I think you should check out mkstill in bellman. It takes a stator and minimises it. For example, your two-eater combo can also be made much smaller:

Code: Select all

x = 13, y = 15, rule = B3/S23
2o3b2o$2o2bobo$4bo$5o$o$b4o$5bob2o$b2o2bob2o$bobobo$2b2ob6o$10bo$7b2ob
obo$8bo2b2o$6bobo$6b2o!

Try to add some "checking" feature to your program, in which the search program checks the population, and continues the search to see if it can gain a smaller population.

I think it is clear now that I may abort the LWSS-to-G project due to difficulties. Maybe a HB*H conduit which don't change the glider color. How can I use Hersrch to find such conduit.

The LWSS-to-G is not nearly as difficult as it looks. Please don't give up quite yet!

There's a simple solution, and you have two different paths to find it now. Probably you've already tried connecting the pieces, and you think it doesn't work. Maybe last time something got placed one cell away from where it needed to be, and so everything exploded.

The LWSS-to-G will work, though, if you just take everything you've learned and go through the walkthrough again. Just believe everything that that message says. There are more hints in following messages.

Alternate method: if you successfully set up a Hersrch search to connect the syringe to the H-to-boat converter, that will give you the same answer.

I or someone else can put the pieces together for you, if that's what you want. But the LWSS-to-G is a great example of a real record-breaking discovery. The idea was to give you all the tools you need to make the discovery yourself. After all your recent practice making conduits, you're only a few minutes away now.

Please just post something to show what's going wrong when you follow the walkthrough, or when you try to solve the problem with Hersrch. From what you've posted so far, nobody can figure out what's stopping you from taking the last steps.

This *WSS conversion topic has generated some interest, and there's now a solution using a different reaction that recovers a little faster. But it's fairly big and awkward, it takes a long time to produce an output signal, and it may not be possible to reduce it in size without increasing the repeat rate past 508 ticks. So your base reaction can still set a record, for some combination of size and speed.

Posted: **October 12th, 2015, 7:54 am**

I followed the walkthrough. The problem now is that if I use these pieces, the glider released by the H-to-boat would destroy the block in the previous conduit and there is no space for a Eater.

Oh, so that's where the confusion came in -- now it all makes sense! I'm sorry that it took so long to clear up the problem, but you've solved it now.

If the yellow Herschel had gotten to that position by following that previous Bx167 conduit, then it would have left some very convenient junk behind:

So this new LWSS->G of yours actually works after all, and it's repeatable every 508 ticks. And it's only 65x73 -- very nice!

EDIT: There seems to be some tough competition on the Stable Glider Reflectors thread. The discussion here might have generated a little too much interest, at least in terms of holding on to the record for smallest fastest LWSS->G for very long...!

You don't really need Hersrch for that. Both of the known Bx conduits in Golly's Patterns/Signal-Circuitry/Herschel-conduit-stamp-collection.rle keep the same glider color, I believe. So technically your search is done before it starts.

If you want a B conduit instead of Bx, just try adding an Fx conduit that also doesn't change the glider's color (e.g., Fx153.)

If you really want to run a Hersrch search, you can modify the batch file given here -- the second one, not the first one! Did you try running that batch file, and do you understand the results that come out? What goes wrong when you try to adapt it for your HB*H problem?

To write your own Hersrch -e scripts, it's really good to have some familiarity with basic algebra. How much practice have you had with algebra?

Posted: **October 12th, 2015, 9:21 am**

So, now I breaked the record, what's next?
-PS: I am really good in algebra. I just couldn't understand the variables to put in Hersrch in the batch file.

You can decide what to do next. Sounds like you're getting started on writing Python scripts. If you run the working examples (the one that I posted, and several more sample batch files that come with the Hersrch package) and look at the (X,Y,T) offsets of the conduits that Hersrch reports for each search, you should be able to make sense of the scripts that generate those conduits.

-- If you post nothing more than that you "couldn't understand the variables", I don't know how to help. Specific questions would be good. Would it help if I posted a Hersrch batch file that finds your LWSS->G?

Thanks to all the interest in the problem, I'm afraid that your LWSS-to-G record might not last very long (!). It depends on whether someone can find another H-to-2G that's a little shorter than this one, based on an F171 conduit:

This 62x80 is already within 215 cells of your 73x65, and it recovers in only 444 ticks. Maybe you can look through the H-to-G collection and find a smaller H-to-2G that works -- it mostly just needs a NW glider of the right color.

Gustavo6046 wrote:Have this reaction any hope in ptbsearch?

I could be wrong, but I don't see any likely applications. You're destroying a long boat, which is relatively rare and very hard to restore. In fact, nobody has ever done it, at least in a usable conduit.

More important, there's already an ultra-compact direct MWSS->G.

So even if you end up finding an MWSS->Herschel converter, let's say, it would have to be somehow better than attaching just the MWSS->G to a syringe -- which is really pretty good, in terms of bounding box, repeat rate, and flexibility (you can move the syringe relative to the MWSS->G, to make the circuit fit into a larger pattern).

Out of curiosity -- what made you believe that ptbsearch might be able to do something with that reaction?

Here's another request: could you post all your "I don't understand" and "can't make this work" posts here on your thread (only) -- maybe with links to the other threads you're interested in? If there's a discussion going on in another thread, then a short "I don't understand" post seems like an interruption, not part of the conversation, so it will tend to get ignored.

We were already talking about Hersrch in this thread. It's very difficult to tell what's going wrong in a case like this, unless you're a lot more specific.

If you want to get other people to help you, you have an important responsibility yourself. Describe the problem so carefully that someone else can do exactly the same thing. How could I do something to see exactly the same "tons of unrelated conduits" that you're seeing?

A rectifier may actually work better than a Snark for this particular setup:

If the rightmost eater is removed in the lower converter, it forms a useless backward H-to-R.

Thanks guys!

I have some hints that can help manual Eater placement.
- It will work 82% of the time if you place it where the non-Eater green cells are alive and the red one is not.

Code: Select all

x = 7, y = 6, rule = LifeHistory
4.BAD$4.B2A$2.2AB$.A.AB$.A$2A!

And more hints in Eater placement:
- It will work more of the time if you put it to eat smaller patterns and non-repetitive ones, and this will also leave less junk.
Check this H-to-Block. No eater can eat the block as the pattern that precede it is repetitive. Anyway is it useful?

Code: Select all

x = 22, y = 28, rule = LifeHistory

So, with basis on that I experimented perturing the evolution of a G-heptoplet.

And also done so to a tap-nonomino so that it output a Pi and a glider:

Tangential note: only one of those two eaters at the bottom is necessary. It's good to check each catalyst and see if it's really just perturbing a spark that would have died anyway.

Try the following experiment and you'll be able to answer your own question about usefulness.

Start with a standard Herschel conduit -- let's say the F117.

Code: Select all

x = 45, y = 22, rule = LifeHistory
22.2A$23.A$10.A11.A$10.3A9.2A$13.A$2A10.2A$.A$.A.A$2.2A$25.2A15.C$25.
2A15.C.D$42.3C$44.C3$2.E$2.E.E$2.3E$4.E11.2A$16.A$17.3A$19.A!

Run it and see what happens.

Now delete the leftmost eater and run it again.

Compare the location of the block that shows up, to the location of the block in the H-to-block you just posted.

Think about the purpose of Herschel conduits -- moving signals from one place to another.

1) Will it be very useful to destroy a Herschel signal and get nothing but the block that the Herschel naturally generates anyway?

2) I've tried to get this idea across to you before: if you start with a Herschel and add a couple of standard catalysts by hand, you're very very unlikely to find a useful converter that no one else has ever seen.

It's not even worth asking about or posting this kind of thing, unless you can make it useful yourself! Build it into a new mechanism that's smaller or faster or quicker to recover than the best currently known pattern that does the same thing -- then people will certainly take an interest in it.

There has been a lot of interest in Herschels over the years, so many other people have already done exactly what you're doing now. People were running search programs to find conduits with twice as many catalysts as that, back in the 1990s.

Treasure-hunting is fun, but it usually works better if you look in places where other people haven't looked yet.

This will be the last question from me for a while.

You still seem to be looking for useful signal circuitry. Remember that Conway's Life is a "zero player game" where you're really not supposed to stop in the middle and draw in whatever shape you want.

So... where are your "G-heptoplet" and "tap-nonomino" going to come from? Can you create a circuit that outputs one of these, in such a way that the catalysts you've posted have room to work on them?

That's a really painfully difficult problem to solve in general, and it's going to be your job to solve it for this case. Nobody else is likely to be able to do that for you, even if they wanted to. It might take months of running a customized search program.

Now, if someone did spend those months to do that research for you, what would they have in the end? ... A blinker. An output glider. Maybe a pi output, too, in the second case, if by some miracle the input conduit's catalysts didn't get in the way.

There might be an easier way to make a blinker. Have you tried removing eaters one at a time from an Fx77 conduit, for example?

It doesn't do what you are saying it does. No R is ever generated there.
