Re: Glider Guns of large periods

@dvrgn - oops... I thought this is the accepted rule (for me it seems to be the most natural). Due to the fact I didn't wanted to maintain another list of "smallest guns" by some another arbitrary criteria, lets for now accept Jason rule. Considering the fact that Jason has one of the most linked li...

Re: Glider Guns of large periods

Well I suggest to add in the first post of this thread, all the improvements we find here of Jason's p14-1000 gun collection, because after p1000 it's too much even for me... Although with obvious design, Herik's p512 is improvement on the existing model in the collection, so I will add his gun firs...

Re: Serizawa - Linear Self Replicator.

I was thinking along those lines, and on my opinion it's simply more elegant to add extra self destruct circuitry. Here is all it takes for the self destruct circuitry. x = 459, y = 274, rule = Serizawa 39$361.A.A2.A.A$362.B4.B7$431.A.A$362.A.A67.B$363.B8$426.A.A2.A.A$ 427.B4.B22$425.A3.A4$361.A3.A5...

Re: Serizawa - Linear Self Replicator

About Self replication there is definitely a confusion of a kind. I would consider it self replicator the same way Gaoucher's self replicator (in Nobili's rule) is replicator. I think the original Von Neumann replicator is linear replicator as well. Also in Codd's rule all the replicators are of thi...

Re: Glider Guns of large periods

I think the challenges in this area are:

1. Update the collection of smallest glider guns, using the new discoveries.
2. Write scripts that create small guns (i.e. O(log(N)) of any arbitrary large period.

Re: Glider Guns of large periods

Well using hershels is nice, but it has the same size problems as any other approach, that doesn't uses back firing. The only advantage of hershel tracks that they can be made to produce any arbitrary period with only one instance of gun (i.e. true period). P60 technology can make any period with 60...

Re: Glider Guns of large periods

Well the problem with using only multipliers is that it's just gives you "power series". I mean if you have a p60 gun you can make p60*2^N or p60*3^N, but for the ability to make it of every period (prime as well), one should use the "back firing glider technique". This allows creating relatively "s...

Re: Glider Guns of large periods

@towerator - I think the logarithmic bounding box glider gun is a new idea. Usually the glider guns are polynomial. Also it's not obvious to setup any period, because the "N state" machine allows glider guns "powers". i.e. two state machine is obviously allows 2^N state machine and a glider gun mult...

Serizawa - Linear Self Replicator.

Serizawa rule is perfect for self replicators and universal constructors, but until now there was no known specific examples of such. Here is a working Universal Constructor based self replicator (Geminoid) in Serizawa. It's P13,362,290 with (2444, 3219) step. The Geminoid is attached. You can also ...

Re: Glider Guns of large periods

Having glider gun of any arbitrary large period is not a big deal. Due to the fact that reflectors and duplicators are known, one can create glider guns as follows: x = 55314, y = 717, rule = B3/S23 97b2o1398b2o1398b2o1398b2o1398b2o1398b2o1398b2o1398b2o1398b2o1398b2o 1398b2o1398b2o1398b2o1398b2o1398...

Re: Glider Guns of large periods

Yep I noticed the redundant parts. Here is a general concept of how an o(log(n)) glider gun can be built for any period. The main idea is that the "vibrating" blocks that actually represent the binary code of "current state", can be manipulated after the glider is "shoot" out to fit any needed perio...

Re: Serpinsky Glider Gun

This is interesting. With this "two state machine" one could create 60*2^N glider gun with o(N) components. For example P60 * 256 can be made with much smaller bounding box: x = 0, y = 0, rule = B3/S23 15$57b2o$57b2o$19b2o$18bo2bo$19b2o$11bo36bo$10bobo2b2o8bo22b3o$10b2o3b 2o6b3o25bo$22bo22b2o3b2o6b2...
