Can this rule be fixed so that when state 2 survives by S3i, it becomes state 4? The line 2,b1,b2,0,0,0,0,0,b3,4 doesn’t seem to be working.

Can this rule be fixed so that when state 2 survives by S3i, it becomes state 4? The line 2,b1,b2,0,0,0,0,0,b3,4 doesn’t seem to be working.

You'd have to put that line in as the first survival rule, or somewhere toward the top anyway. Currently 0,b1,b2,c,c1,c2,c3,c4,b3,1 is going to take precedence.

(EDITed the line that triggers -- I read it wrong the first time.)

[confocaloid]

[...] The line 2,b1,b2,0,0,0,0,0,b3,4 doesn’t seem to be working. [...]

The rule "d,b1,b2,c,c1,c2,c3,c4,b3,1" will be followed instead, due to appearing earlier in the file and matching all cases when "2,b1,b2,0,0,0,0,0,b3,4" could possibly match. (The variable "d" can take value 2, and the variables "c", "c1", "c2", "c3", "c4" each can take value 0.)

A likely solution would be to move that line up, so that it would appear above "d,b1,b2,c,c1,c2,c3,c4,b3,1" at least. (Where exactly, depends on how you would like the rules to work.)

Trimmed file with relevant parts:

Code: Select all

var a={0,1,2,3,4} ...
var b={1,2,4} ...
var c={0,3} ...
var d={1,2} ...
...
# Survival
...
d,b1,b2,c,c1,c2,c3,c4,b3,1
...
2,b1,b2,0,0,0,0,0,b3,4
...

[...] Currently 0,b1,b2,c,c1,c2,c3,c4,b3,1 is going to take precedence. [...]

"0,b1,b2,c,c1,c2,c3,c4,b3,1" cannot take precedence over "2,b1,b2,0,0,0,0,0,b3,4" because the former rule can only be followed when the middle cell's current state is 0, and the latter can only be followed when the middle cell's current state is 2.

this 1d rule from a CA textbook i was reading (would appreciate it if the rule worked similarly to W rules where time goes down)

No, I assume nothing happens

[...] Does the book say anything about what to do if neither of the listed rules applies? [...]

[...] No, I assume nothing happens

I assumed "stay in the old state unless some rule prescribes otherwise".
(It is interesting that those six rules can be read in any order, without changing the effect, as at most one of them applies for a specific cell at a specific time. Also, for all six rules, the future state of the cell in the next generation differs from its current state, which makes the nothing-happens assumption more plausible.)

Taking into account the requirement "... where time goes down", however, that becomes a separate catch-all rule at the end, which is necessary merely to be able to "do nothing":

Code: Select all

0, y,z,0,0,0,0,0,x, y

Without that rule, one would get the following instead:
