Techniques invented by digital organisms
Unrolling the loop.This is a well-known optimization in the copy-process but look at this code fragment, the duplication of the subsequent two instructions are not obvious:

label-b
copy
inc
copy
inc
 if-n-equ
jump-b


(MarVM code)

Lazy replication.Performing computations makes the organism faster but replication takes time from computations. How to balance? A surprising solution is lazy replication. First the organism makes an error when measuring itself consequently the copy process cannot start: the first round is for the computations fully. In the next turn the replication begins but with higher speed.

Graphs describing the dynamics of digital evolution
The fitness curve of a typical run - it seems that there aren't enough task to learn:


The effectivelength (number of executed instructions) in an other run.


The lifetime distribution of organisms. (does it indicate self-organized criticality?)


The graphs were made by Gri and R
