Stable relationship

In the previous experiment the impact of the CAs on each other was positive. As impact rose their cell content and cell production also rose.  Yet  this relationship was unstable since every impact couple generated a different CA configuration. Impact lowers the age of death. If intensive the CA  produces more (dead) cells, yet tends to die from exhaustion .. When impact lessens, CA becomes immortal and does not produce any cells.

Hitherto age distribution of one CA depended on the state of the other. In the present experiment,  age distribution of one CA depends  also on cell production of the other. When impact is positive, state and production lower the death threshold. When impact is negative, state and production elevate the death threshold.

Impact (i)  < 0 ;{age (j) depends on state(i) -  cell production (i)}
Impact (j)  > 0 ;{age (i) depends on state(j) + cell production (j)}

The upper contour plots depicts the effect of impact on cell content (CA size). The lower contour plot depicts the effect of impact on cell death (cell production). The plot is divided by linear ridges in which CA structure does not change despite great variation of impact. Like the ridge of 2582 cells which extends from impact {-8, 0} to {-8, 6} .  Or the ridge of 2910 cells which extends from {-6, 7} to {0, 7}.

The lower contour plot indicates that in some ridges cell production is constant. Like in the ridge {-8, 0} -> {-8, 6}.  In some regions CAs are more fertile, and in othes, less fertile.

The lower image depicts representative CA couples. In  the first couple {-8, 1},  One CA is immortal and sterile, while the other produces all the cells. Yet the first is as important to the joint cell production since it contributes stability. In the second couple  in one CA 2440 cells produce 6 dead cells . In the other, 470 cells produce 15 dead cells. The latter is therefore more efficient. The last couple is fertile and unstable.
