[GAME] Building CA from the Ground Up

[R2INT]

Midnight, Day 5

Later on Day 6

After investigating the image for a little but, it appears that the CA is 2-dimensional and uses the neighborhood shown here:

Code: Select all

  . 
 .O.
  . 

where . is a cell inside O's neighborhood. It looks like that the image is of a CA where a cell is born if it has 1 vN neighbor. Here are the first few generations:

Code: Select all

O

.O.
O.O
.O.

..O..
.....
O...O
.....
..O..

...O...
..O.O..
.O.O.O.
O.O.O.O
.O.O.O.
..O.O..
...O...

Even later on Day 6
I take cross-sections of the image.

Code: Select all

    o
   o.o
  o...o
 o.o.o.o

Wait... isn't that a 1D CA? Let me check my rule chart...

Code: Select all

100 = 000 001 010 011 100 101 110 111
       0   1   0   0   1   0   0   0 = 72

This new 2-dimensional CA seems to be emulating rule 72 in 2 dimensions!

Cool! Looks like another 2-dimensional neighborhood:

Code: Select all

Day 8

I just found that all cellular automata could have logic of some sort; proven simply because all such functions have conditions, and conditions bring logics, logics bring computations.
