artificial life behavior. The other is using the biological devices to construct
life systems. All of them are called bio-computers, which can be regarded as
a method to approach the artificial life.
(2) Use computer simulation technologies to study and develop the software
model, which can exhibit the behavior characteristics of life bodies. In short,
both of neural network and genetic algorithm adopt the mathematical model
of information to simulate the creation of artificial life.
(3) Based on working principles, use computer simulation technologies to
generate the life bodies. The foundation of the life phenomena is becoming
disorderly and unsystematic with increasing of physical entropy. The
principles of this phenomenon are chaos fractal, dissipative structure,
concerted reaction, etc.
(4) Through computer simulation, analyze the characterized behavior producing
of life, set up new theory. Utilize the 3 strategies above to get the general
properties of the life behavior. By summarizing, set up the basic theories of
life. This strategy forms the theories of self-organization, hyper-parallel
processing, etc.
The above 4 research strategies of artificial life, accept a lot of concepts and
inspiration from the real biological information processing systems, which
construct life using artificial media such as computers, etc. The life concept of
real true living beings is abstracted, generalized, and extended. The achievements
of artificial life research take the molecular biology of reductionism as the center,
which can be regarded as the supplement of modern biology. The mechanisms of
life behavioral information processing, such as abstract, generalization, and
extending, can be applied to the fields of precision mechanisms, control
engineering, computer science, etc. The artificial life is the great force for
forming the new information processing system.
One of the goals of artificial life is to extend experience database used in
establishing theories. One kind of methods is to create processes in computer.
While other artificial media which can represent life-like behavior, have no
explicit simulation and concrete known organism model.
Von Neumann researched on construction related self-reproduction. He found
there are two different ways can be used to describe organism heredity:
(1) Interpret the commands and construct descendants,
(2) Do not explain the data, but only replicate it to the created description copy,
and then hand it down to the descendants.
