When searching for conduits, it is not unusual to find a recognized output as well as some still-lifes and oscillators or an active region either just behind the output region or near/just behind where the input region was, i.e. a messy conduit. Sometimes, these can be treated as partials and cleaned up, but even if not, it's still useful to keep track of messy conduits because it's possible that two messy conduits can be appended to each other so that their messes annihilate each other. Here's an example of such a messy conduit. (It's periodic, but it can probably be made stable.)

Code: Select all

x = 91, y = 63, rule = B3/S23

As the above pattern demonstrates, the conduit works if the century has certain active regions (the pi) or stable objects (the loaf and blinker) behind it. If someone finds a conduit that creates a messy century, it's possible that the two conduits could be combined to produce a clean C→G, but we'll never know unless we keep track of the dirty conduits that we find.

we'll never know unless we keep track of the dirty conduits that we find.

Haven't you shown a full example where a dirty conduit was cleaned up by the next conduit?

Haven't you shown a full example where a dirty conduit was cleaned up by the next conduit?

It was technically a dirty version of RF28B, which already had clean versions, but I guess that it still counts. Thank you for reminding me of it. The example is here.



Edit: I just realized that the junk is actually blonk-tie.

Yes, I also think like you.
But as beginner I am, I only find a cheap stable way to clean one junk (the boat).

About stable glider reflectors, is there 180° with +1 , +2 , +3 half diagonal ?
I often need this reflectors to have a solution of my experiments.

About stable glider reflectors, is there 180° with +1 , +2 , +3 half diagonal ?
I often need this reflectors to have a solution of my experiments.

I think compact stable 180° glider reflectors are an unsolved problem, for many lane/timing combinations.

It is possible to assemble an engineered 180° glider reflector, for example using Snarks, a syringe, some Herschel conduits and an edge-shooting Herschel-to-glider converter. But it will be large and slow.

In many cases, there should be more compact periodic solutions. For example a single pentadecathlon can do 3hd:

Code: Select all

x = 52, y = 24, rule = B3/S23

Edit2:
Here's a dirty H-to-R.
But not sure the R output can be well get out.
I show the H-to-R connected to RF28B, but the B output hasn't a good clearance.
Perhaps someone can do a better connection and find a way to cleanup ...

After 2 weeks, is it a double post ?

Here's some dirties dependent H to nG (n=1,2,3).
The 3rd in the 1rst row is solved here : viewtopic.php?f=2&t=1849&p=176832#p176832
The preH-to-LongBoat+G is interesting because the LongBoat can be used in 3 ways (2x180°+1x90°).
The others are almost interesting to because they leave only 1 still life.
So they can be considered like SL-Factories + Gs

Here is a dirty HFx140H with an annoying Behive :

Code: Select all

x = 74, y = 54, rule = LifeHistory

And a dirty H-to-2G with an annoying Blinker :

Code: Select all

They are somewhat less annoying since the big catalyst can be replaced with a Spartan constellation viewtopic.php?p=167364#p167371

Edit:
The Fx140 is almost a Behive Stopper :

Code: Select all

Why "almost"? I think it is already a working glider stopper, especially in the Spartan form:
