The previous experiment showed that information storage is still cumbersome. On the other hand, information retrieval is simpler. We start with two synchronized oscillating CA with a period of 46 time units. The experiment starts when both reach state-i, and CA-2 starts losing age at a rate of one age increment per step. Cells with less age die sooner than cells with more age. By t-35 all cells are dead. The third figure under CA-2 depicts the loss of cells with time. CA-2 differentiates with time.
The 35 states of CA-2 may be regarded as a memory which stores actions, which can be visualized in the following way. Each state at a time is copied to CA-3. The outcome is depicted below. States copied between t = 1-4 had no effect on CA-3 behavior. Next, is depicted the outcome of copying states 5 to 6, then states 7 to 11, and so on. Altogether CA-2 memory stores six different actions.
In CA-2 context, each of the 35 states leads to its death. It is an apoptotic process. Yet when copied to CA-3, only states 34 and 35 kill it. In the context of CA-3, all other states acquire a different meaning. The two CA vary in their age structure.
This simple memory does not require any storage device! Suppose that CA-3 wants to recall state-7, the state of love. Remember that CA-3 cycles through 46 states. When arriving at state-i , it stops CA-2 aging, waits seven more time units, copies the required state and falls in love. Later on CA-2 disappears, which saves resources. CA-3 makes love for a while until being replaced with a zygote which later on assumes the 46 period cycle.
A retrieved information is useful if it leads to
Recall is a perturbation with four kinds of outcome:
1. No change (States 1-4)
2. A new stationary oscillator. (All states except 34 and 35)
3. Transient oscillations (States 7-11)
4. Death (States 34-35)
