Mutual Impact

Hitherto we studied various aspects of CA mutual impact:
1. Both CAs control each other.
2 .Impact and cell production.
3. Stable relationship,

In all three experiments, impact ={i, j} was driven by the program. In the present experiment CAs  adjust their mutual impacts so as to produce more cells. In the graphs, CA-1 is depicted by  solid lines and CA-2 by dashes.

Program outline

Step  = 0.  Set the initial conditions:

1. Two zygotes are planted  (their color =1)
2. The rule  = #600
3. Initial  impact ={i0,  j0}  which sets the initial death threshold.
4. Create a cell production register cell(previous) = 0.

Step = 1.

Let  the CAs grow until reaching their maximal size (steady state). Their cell production is stored in a register.= Cell(now). The difference between cell(now) and cell(previous) sets the new  impact = {i1, j1}. Store cell(now) in cell(previous). Plant two zygotes. Go to step =1

Stop when each of the two zygotes fails to generate a CA


All states in a CA may be updated in parallel. You plant two zygotes and let the CAs evolve into their maximal size. From then and  on you may update their states (rows)  in parallel.  During each step the entire CA is updated. It stores its cell production / step in cell(now) computes its new impact, and adjusts all its states (rows) in parallel.

Holocrine secretion

As cell production rises the CA is filled with white cells. This space is called vacuole. This phenomenon is observed in sebaceous glands, and called holocrine secretion. Vacuole size is proportional to cell production.Throughout the experiment the two CAs stimulate each other more and more until they die from exhaustion.
