Links tuning

We continue to investigate the four CA proliferon adjusting links between CA  in order to stabilize it. The objective is to avoid instantaneous changes like killing a CA  and allow the proliferon to set its limits, e.g., maxwidth.
maxwidth = Min[tolerance[0] / 100, 60]  ;  Maximal CA width  is set by CA-0

In the previous experiment CA-3 was  pacing the unit. Here it determines the maximal tolerance of CA-1. 
If[ tolerance[2] > tolerance[3] - 1, reduce tolerance{2], reduce tolerance[3]]

CA-1 and CA-3 feed CA-2 the accumulator with their daily tolerance production:
delivery[2, 1, Min[maxwidth, tolerance[3] / 20 , 2] ;
delivery[2, 2, Min[maxwidth, tolerance[3] / 20 , 2] ;

Proliferon size depends on CA-0 tolerance. When the CA-0 zygote is planted its tolerance = 1.  As the stem process grows it accumulates tolerance, becomes more vigorous and supports better the other CA.
If[ p[1,prev] > p[1,now], set rule[1392]; else [set rule[1167]]
If[ p[2,prev] > p[2,now], set rule[1392]; else [set rule[600]]
If[ p[3,prev] > p[3,now], set rule[1284]; else [set rule[600]]

When  the experiment starts,  CA-0 plants three zygotes. The three CA switch  between two rules as specified above. CA-1 delivers its  daily product to CA-2  (accumulator). CA-3  does not deliver tolerance. The experiment lasted 4000 time units (days).

CA oscillations are linked with their output. When the curve rises the CA accumulates resources and when  it  declines CA releases them.

The graphs below depict a running mean of CA tolerance, and its running variance. CA-0 is isolated and its mean and variance are the lowest. When CA interact their mean tolerance and its variance rise. Roughly, mean tolerance is proportional to tolerance accumulation, and variance is proportional to output.
