### Re: Thread for basic non-CGOL questions

What is the smallest (known) log-growth pattern in any isotropic non-totalistic Life-like cellular automaton (without B0)?

Bonus: And log(log)-growth?

What is the highest (known) period for an unloopable (loopability 1) RRO in isotropic non-totalistic Life-like cellular automaton (without B0)?

Are there any guns for hybrid Gs in Quadlife or Immigration?

For instance, these:
Or, perhaps my question would be better phrased:

Are there any synths for hybrid Gs in Quadlife? (since it can emulate immigration, I won't ask about immigration)

Here's a tricolor HF synth, to demonstrate that such things are possible:

This R surprised me:
EDIT:

More proof of concept-- a BH with a foreign cell:
Similar:
Anyways, back to my question. Can anyone make a synth of this?

If it helps, the distinct 2-color 2G collisions. Two asymmetric ones have multicolored output objects:

Can someone apgsearch quadlife?

Is there a thread for this rule? There was discussion of it while back in rules with interesting failed reps:

### Re: Thread for basic non-CGOL questions

No. Partitioned CA do not use an alternating neighbourhood such as Margolus rules do. Instead, each cell is divided up (partitioned) into as many parts as the cell has neighbours. So for a 4-neighbour PCA, each cell has 4 parts. These parts are denoted as U(p), R(ight), D(own), and L(eft) in the paper referenced by the PCA thread. Each part has it's own state (0 or 1 for a 2 state PCA). A 2 state PCA with 4 neighbours is denoted as a 2PCA(4) cellular automata. The evolution of the CA is determined by a local function which maps from 1 part of each of the 4 neighbour cells to the 4 parts of the centre cell. Here's a little diagram which shows the four parts of a central cell and it's 4 neighbours. The state of the four parts in the central cell (u, r, d, and l) is entirely determined by the four parts labelled U, R, D, and L from the neighbouring cells (i.e. a cells current state does not influence it's resulting state)Gustone wrote:Is PCA margolus

This includes birth and survival configurations, so the number of neighbourhood configurations is 4274.

### Re: Thread for basic non-CGOL questions

Actually, this is clearly not the desired sequence, though I'm presuming that the term for n=2 matches the 1D case coincidentally. I'm fairly sure there'll be no such coincidence for n=4 - I see no reason why the number of 4x4 binary matrices under D_4 should be the same as the number of 3x3x3 binary matrices under the octahedral group O_h, which is what we actually want to know.wildmyron wrote:I believe the answer is 8548, given by the sequence A054247:muzik wrote:How many different conditions does the range-1 Moore 3D isotropic non-totalistic rulespace have?Number of n X n binary matrices under action of dihedral group of the square D_4.

### Re: Thread for basic non-CGOL questions

If time is continuous then space is necessarily also continuous since you can't have a cell sitting in between two discrete borders - or else what's the point of continuous time?

### Re: Thread for basic non-CGOL questions

Here's an example of a geophysical model which uses a discrete lattice but continuous time. Of course the implementation of the model is not actually continuous, but an approximation to it. The framework models continuous time by determining the probability of a transition occurring between every pair of neighbouring cells within a small dt, and stochastically (randomly) determining whether a transition occurred for each cell pair within every dt. With small enough dt this becomes a good approximation of continuous time. I've only skim read the paper so I hope I'm not misrepresenting it.

Have you been through the original article from 1996? Here's a link just in case.

### Re: Thread for basic non-CGOL questions

The most straightforward way to get exponential growth would be to work on a regular tiling of a hyperbolic surface (where the angles of a triangle sum to less than 180 degrees). For example, such a surface could support a tiling of regular octagons, where each cell has eight neighbours, but the number of cells at distances of 1,2,3... increases exponentially.
