Two rules
The CA is controlled by the following buttons:
Start: CA are planted.
Hide CA-1 Hide CA-2
Out CA-1+: raise output rate Out CA-1-: reduce
output rate Out CA-2+: raise output rate Out CA-2-:
reduce output rate
Infection: Infect CA-1
CA-rule: Toggles between rules 600 and 624.
Information:
Input rates Output rates.
Click on Start
and then Hide CA-2. After a while click on CA-rule.
Now rule 600 is replaced with rule 624. Despite its different
structure, then CA behaves like those in previous experiments.
Let the CA evolve and click again on CA-rule to restore
rule 600. Repeat it again and observe the CA transition when the
rule is toggled. There are two transition possibilities:
1. The last state before switching serves as an initial state
under the new rule, and a new state is generated.
2. The last state does not serve as an initial state and it dies
whereupon the CA plants a zygote which then evolves under the
new rule.
CA-[rule=600] traverses 46 states which belong to a CA- solution
set (*ca158. In other words, under the rule 600 they all will
end in a solution. CA-[rule=624] has a different solution set.
Not all its states may serve as initial states for the CA-[rule=
600]. If following rule switching from 600 to 624 the CA continues
undisturbed, the last state under rule=600 may belong to both
solution sets and vice versa. However you can’t be sure since
the process may die after several states whereupon a new zygote
will be planted. Which would indicate that this state does not
belong to both solution sets.
You may now repeat the previous experiments: Click on Infection, or change the output rates. In between toggle the CA-rule. After a while the system will settle at a solution (attractor)
