**Parallel non linear computation**

A zygote is planted and evolves into a stem process. During each iteration, all CA cells are updated in parallel. Each iteration is a parallel
non-linear computation. Initially CA traverses a non-stationary phase
which ends at t = 16 whereupon it starts oscillating
. This phase is called a solution of the
system. Since CA is isolated, it does not attain any other solution**f[state[j, i], rule[#], age]**.
Its **solution** may be defined as **f[state[j, i], rule[#], age]
= k, **where k is the **center of mass** around which CA oscillates.

We now return
to the Isocitrate,
a-Ketoglutarate transition of the previous experiment. We might study it in vitro. We add all
the ingredients: Isocitrate, NAD, and pro-dehydrogenase
into a beaker and observe
the transition. The transition will not be complete, and the two molecules
will settle at an **equilibrium. **

This transition may be expressed also in form of a general chemical reaction equation in which reactants A and
B react to give product C and D.

*a*** A + b**

**[C] c**

Ultimately,
Isocitrate, and a-Ketoglutarate will settle at this constant, which is the
**solution of this isolated system**.

A similar ratio between
the two molecules will be maintained also in the
citric acid vortex. It may differ from the above, yet
**k will remain constant.** We are sill dealing with an equilibrium yet it differs from that of the
isolated reaction. Since all constituents stream, this **equilibrium is called homeorhesis**.

In the narrow isolated context (in vitro), **k depends
only on the reactants**, which will determine when and how the system will reach an equilibrium.
In the wider context, **k
depends on all processes
involved in the entire vortex.** **k**
is a solution of the system. In the wider context **k** is only
one computation in a vortex, since a solution involves many computations

Yet
even this solution is incomplete since many other processes in the body
contribute to the citric acid vortex. This process
set is called here **WOB**. The entire WOB determines the** **outcome
of the** **Isocitrate,
a-Ketoglutarate transition**. The vortex is a projection of
the WOB solution on a lower dimension**. Actually all events in the organism are **systemic** even if appearing as localized.
When I raise my hand the entire WOB settles at a
solution involved in raising my hand.

**Artificial Life (AL)**

None
of the
current AL tools can simulate even a simplified
citric acid vortex. Not even a
DNA computer can do it. CA
is the best available tool for this purpose.
By now we know how to program proliferon solutions. Our next objective
is to search for optimal solutions, or
**let a multi-proliferon system to find its optimal solution**.
