The notation of a rulestring is as follows (subject to change, if anyone has any better suggestions reply with them):
BA - conditions for a state-1 cell to be born
BB - conditions for a state-2 cell to be born
TA - conditions for a state-1 cell to become a state-2 cell
TB - conditions for a state-2 cell to become a state-1 cell
SA - conditions for a state-1 cell to stay alive
SB - conditions for a state-2 cell to stay alive
Conditions would be a string of two consecutive digits, with the first digit specifying how many neighbouring state-1 cells and the second digit specifying how many state-2 cells. The sum of the consecutive digits cannot exceed 8. A condition cannot be for both transitioning and surviving for a cell. For example, this would be the three-valued replicator rule (with a lot of transitions since that's how XOR rules work):
Code: Select all
x = 1, y = 1, rule = BA020508101316212432354043516270_BB01040712152023263134425053_TA01040712152023263134425053_TB020508101316212432354043516270_SA020508101316212432354043516270_SB01040712152023263134425053 A!
This would allow for the transcription of a broad range of rules (3^27 if I'm not mistaken), but this is only the tip of the iceberg compared to the isotropic non-totalistic extensions to this rulespace I'm currently working on notating.
