Thread for basic non-CGOL questions

[Moosey]

Is it possible to have a rule where (stable, at least) object (or even just spaceship) speeds are bounded above some unreachable limit, say, c/2, and for any reachable speed there exists a higher reachable speed; that is to say, any (stable) object (/just spaceship) that exists in the rule can be caught up to by a spaceship (of higher speed)?

This would be interesting because it trivially implies that no object can be fast enough to be unreachable-- a phenomenon which crops up a lot in a lot of rules, incuding most visibly B2 rules; any domino with nothing in front of it or within two steps to its sides cannot be stopped from travelling at C forever. A similar phenomenon exists even in GoL; a sufficiently distant LWSS travelling through empty space away from some object is unreachable by said object (sure, you could send a superstring at it, but for any object with a certain horizontal width there is a distance such that the LWSS is unreachable even that way since the superstring's distance it could travel is bounded above by approximately the quantity of generations, divided by two.[citation needed]

The cool thing about the rule I described is that since (stable) object (/just spaceship) speeds are bounded above by an unreachable limit, all spaceships can be caught up to by an even faster ship.



EDIT: unrelatedly, what's the checkerboard dual of B3/S234c?

unrelatedly, what's the checkerboard dual of B3/S234c?

On white cells it behaves like B1e3ajkr5inqy7c/S1e2ei3ajkr4jr5inqy6cn7c8, while on black cells it behaves like B1e2-cn3-inqy4-ny5-ajkr6-ei7c8/S01e23-inqy45-ajkr67c8.

Here is a rule similar to what you are asking. If you could find a rule with similar mechanics where an adjustable spaceship is faster than all other kind of spaceship, I think it would meet your requirements. This one would not work because the small ship at the back is faster than all these adjustable ships.

After few days of LLS searching, I found new type of adjustable spaceship using c2o wickstretcher and a c2o spaceship.
If following spaceship hits the tail of the wickstretcher, then chasing spaceship is delayed and the line wickstretcher start to burning while the "fire" reach to the front of wickstretcher then wickstretcher delayed too.

Delaying an 1 generation for every collision, speed is (12+2*n)c/(25+4*n) for n>=0

I also trying to find other adjustable spaceships advancing or shifting instead of delaying them or using other speed such as c3o, c4o, c5o, 2c5 and 2c3o or faster speeds.
Furthermore, I'll also try diagonal or oblique design if possible.

[wwei23]

What spaceship speeds in Gems have been ruled out at what widths?

[LaundryPizza03]

From this thread:
c/4o, width 16 even
c/5o, width 25 odd
c/7o, width 19 odd
c/7o, width 18 even
c/7d, width 15 bilateral
c/9o, width 15 odd
c/9o, width 16 even
I'm currently searching for even c/9o at width 18.

I believe it's a tagalong, since the bottom segment doesn't work if the supporting ship is removed.

[wwei23]

Why are Corderships so much harder to find in B3/S236e, the one other rule where the switch engine works?

[goldenratio]

Is there even a way to stabilize the switch engine in that rule at all? I tried for about ten minutes and gave up.

[wwei23]

Is there even a way to stabilize the switch engine in that rule at all?

I was able to make these three corderships from the things in my cordership collection that actually worked at all. Two are mutually-canceling puffers, and one just happened to work in this rule as a spaceship as well.

Is B2-a/S12 really the oldest non-totalistic rule? The HighLife article linked to on the HighLife page describes a rule equivalent to B36n/S23.

yeah, I meant a rule where Ts are (reusably) reflected into Ts and Gs into Gs.

Alternately, a rule with G->G, G->T, and T->G converters will work

Think you're right. From researching the LifeCA archives, it looks like JustFriends was first publicly described by Bell on 2000-06-19 (though he notes that it was originally found "a couple of years" before that) while "Ship" was first described by Paul Callahan on 1994-03-22.

I assume that's Life except for birth in a ship-shaped neighborhood. It supports Highlife replicators as well as some CGOL patterns (p46 guns with a tweak?). I haven't thought about it since then. What's the modern way of expressing that rule? Can you post an example in LifeViewer?

No, by definition a Garden of Eden cannot exist if T>0 and as such cannot be synthesised.

I understand that there are fake gliders and fake LWSSes that travel differently in other rules than Life but have the same pattern as a glider or LWSS, but is there such thing as a fake Cordership? Like a ship made of switch engines, but it moves differently in a different rule than it does in Life?

[yujh]

I understand that there are fake gliders and fake LWSSes that travel differently in other rules than Life but have the same pattern as a glider or LWSS, but is there such thing as a fake Cordership? Like a ship made of switch engines, but it moves differently in a different rule than it does in Life?

The switch engine works in B3/S236e (it's the only other rule where it works):

Is there even a way to stabilize the switch engine in that rule at all?

I was able to make these three corderships from the things in my cordership collection that actually worked at all. Two are mutually-canceling puffers, and one just happened to work in this rule as a spaceship as well.

Code: Select all

x = 288, y = 98, rule = B3/S236e

It moves in the same way.

The switch engine works in B3/S236e (it's the only other rule where it works):

I was able to make these three corderships from the things in my cordership collection that actually worked at all. Two are mutually-canceling puffers, and one just happened to work in this rule as a spaceship as well.
