Production controlled by stem process
The previous experiment depicted proliferon production
during a varying demand which was driven by the observer. In the
present experiment production is driven by the stem CA-0. The proliferon
consists of a stem CA-0, and three transitional processes, CA-1, CA-2,
and CA-3. CA-2 gets resources from CA-1 and accumulates them. CA-1
and CA-2 behave like in the previous experiment. Here they are driven

If[ p[1,prev] > p[1,now], set rule];
else [set rule]
If[ p[2,prev] > p[2,now], set rule]; else [set rule]
If[ tolerance/20. > 40, kill[CA-3]]
Before the experiment started, CA-0 planted two zygotes which grew into mature isolated CA-1 and CA-2. When the experiment starts CA-0 plants an isolated CA-3, whose tolerance controls the production of CA-1 and CA-2. When CA-3 tolerance reaches 40 units, CA-0 kills CA-3, plants a new zygote instead and the cycle starts again. When CA-3 tolerance rises, CA-1 and CA-2 switch between rules 600 and 250 in the same way they responded to the rising demand of the previous experiment . CA-1 delivers its daily product to CA-2 (accumulator).
The next experiment depicts the proliferon during one cycle. When the experiment starts, CA-0 plants CA-3 and when its tolerance reaches 40 units (= 200/20.), CA-0 kills it. After that CA-1 and CA-2 also die. They depend on the triggering effect of CA-3 tolerance in the same way as they depended on the triggering effect of demand in the previous experiment .(*
CA-0 triggers the transitory CA at two time points when planting zygote and when killing CA-3. The interval is chosen by CA-0. Whenever CA-3 is killed it is replaced with a zygote. Its survival depends on the tolerance level at which it will be killed. Higher tolerance level will generate longer cycles, and vice versa. If[ tolerance/20. > 20, kill[CA-3]]
